While writing a manuscript for the first time, you might find yourself confused about the differences between an abstract and the introduction. Both are adjacent sections of a research paper and share certain elements. However, they serve entirely different purposes. So, how does one ensure that these sections are written correctly?

Knowing the intended purpose of the abstract and the introduction is a good start!

What is an abstract?

An abstract is a very short summary of all the sections of your research paper—the introduction, objectives, materials and methods, results, and conclusion. It ends by emphasising the novelty or relevance of your study, or by posing questions for future research. The abstract should cover all important aspects of the study, so that the reader can quickly decide if the paper is of their interest or not.

In simple terms, just like a restaurant’s menu that provides an overview of all available dishes, an abstract gives the reader an idea of what the research paper has to offer. Most journals have a strict word limit for abstracts, which is usually 10% of the research paper.

What is the purpose of an abstract?

The abstract should ideally induce curiosity in the reader’s mind and contain strategic keywords. By generating curiosity and interest, an abstract can push readers to read the entire paper or buy it if it is behind a paywall. By using keywords strategically in the abstract, authors can improve the chances of their paper appearing in online searches.

What is an introduction?

The introduction is the first section in a research paper after the abstract, which describes in detail the background information that is necessary for the reader to understand the topic and aim of the study.

What is the purpose of an introduction?

The introduction points to specific gaps in knowledge and explains how the study addresses these gaps. It lists previous studies in a chronological order, complete with citations, to explain why the study was warranted.

A good introduction sets the context for your study and clearly distinguishes between the knowns and the unknowns in a research topic.

Often, the introduction mentions the materials and methods used in a study and outlines the hypotheses tested. Both the abstract and the introduction have this in common. So, what are the key differences between the two sections?

Key differences between an abstract and the introduction:

• The word limit for an abstract is usually 250 words or less. In contrast, the typical word limit for an introduction is 500 words or more.
• When writing the abstract, it is essential to use keywords to make the paper more visible to search engines. This is not a significant concern when writing the introduction.
• The abstract features a summary of the results and conclusions of your study, while the introduction does not. The abstract, unlike the introduction, may also suggest future directions for research.
• While a short review of previous research features in both the abstract and the introduction, it is more elaborate in the latter.
• All references to previous research in the introduction come with citations. The abstract does not mention specific studies, although it may briefly outline previous research.
• The abstract always comes before the introduction in a research paper.
• Every paper does not need an abstract. However, an introduction is an essential component of all research papers.

Abstract Vs Introduction: Key Similarities and Differences

Is an abstract the same as an introduction? This is one of the questions we receive most frequently, so we thought it would be a good idea to write an article about the abstract vs introduction problem. Most students don’t know how to differentiate between the two, especially if they are new to academic writing. Even though the two things are somewhat similar, there is at least one major difference between introduction and abstract. In this article, we will discuss the similarities and differences between the two. What is the difference between an abstract and an introduction? Let’s find out!

The Abstract Vs Introduction Problem

Introduction vs abstract: which one does what? Because many professors don’t explain these two terms to their students, it’s easy to confuse them. We consider that this is not the students’ fault. If they don’t know the difference between an abstract and an introduction, it’s easy to make a grave mistake. Of course, you will get penalized harshly for this. This blog post aims to provide information about abstract vs introduction scientific paper writers need to make sure they don’t get an F on their next essay.

Abstract and Introduction: What Are They?

So, let’s discuss abstract vs introduction APA style. An abstract is basically a summary of a complex paper (such as a thesis or a research paper).

The abstract summarizes all the different parts of the paper, including the research problem, the objectives, the methods, the results, and the conclusion. After reading the abstract, the reader should know exactly what the paper is about and how it is structured. The length of an abstract is around 250-300 words. The introduction, on the other hand, is there to give your readers an idea of what you are about to talk about and introduce your thesis statement.

It can contain a bit of background information, but it does not delve into the specifics of your research methods or results. Also, the introduction does not discuss the conclusion of the paper in any way.

The Key Difference Between Abstract and Introduction

OK, but what is the major difference between abstract and introduction? In simple terms, the abstract is a summary of the entire research paper. It briefly discusses the methods, results and conclusion. The introduction, on the other hand, is there to entice the reader to read the entire paper. It discusses just the background of the problem and the objectives of the paper. You will never see the conclusion being discussed in an introduction.

Is an APA abstract vs introduction different from MLA or other types of academic writing? No, the abstract and the introduction are just as different regardless of the academic writing style. You should never confuse one for the other because the consequences can be a rejected paper or at the very least a very low grade.

Introduction vs Abstract: The Similarities

Now that you know the main difference between an abstract and introduction, it’s time to talk about similarities. This should help you avoid any confusion:

• Both the introduction and the abstract are placed at the beginning of a research paper. In fact, an abstract can be considered a de-facto introduction.
• Both the abstract and the introduction are there to provide some information about the subject and about the objectives of your research paper.
• Both can be used as a way to attract the interest of a reader.

However, this is where the similarities end. Never assume that you can write an introduction in place of an abstract. Of course, you can’t write an abstract in place of an introduction either. This is the information about abstract vs introduction lab report writers need to know before they start writing their first paper. We know that sometimes writing an abstract can be more difficult than the introduction to abstract algebra in high school. However, with practice, you will quickly get the hang of it.

Abstract and Introduction Examples

To help you understand the meaning and role of an abstract better, we have written an example abstract for you and broken it down into pieces:

As of 2023, residual herbicide that is accumulating in certain crops is posing a growing threat to the rice-wheat rotation in northern India. (The background part) When it comes to pesticides and pesticide metabolites, green manure has been shown to stimulate ample co-mineralization. By incorporating it into the soil, the effects of the herbicide residue can be mitigated. (The objectives part) During a three-year study at the North Indian Wheat Research Institute, Azolla Pinata and A. Carolingiana have been used as green manure. The effects of the green manure on the Propanil and Buthachlor herbicides has been evaluated, as well as the mineralization and co-metabolization of the herbicides, using a process known as liquid chromatography. (The material and methods part) Initial results indicate that Azolla Pinata caused the Propanil herbicide to co-mineralize in 14 days. However, the green manure did not have the intended effect on the Buthachlor herbicide during the study. (The findings part) After analyzing the findings of the study, we can say for certain that Azolla Pinata used as green manure can prevent residual Propanil accumulation. (The conclusion part)

An example introduction for the paper would look something like this:

Residual herbicides are posing a growing threat to the systems of rice-wheat rotation in Northern India. According to a recent study by the North Indian Wheat Research Institute, Azolla Pinata is able to co-mineralize some herbicides. Understanding the process by which this happens is important for the future of Indian rice and wheat crops. This research paper aims to answer the following question: how does green manure co-mineralize certain herbicides? We will first analyze the soil and the herbicide accumulation, then we will discuss the effects of green manure, and finally we will analyze the potential applications.

Abstract vs. Introduction—What’s the Difference?

3-minute read

• 21st February 2022

If you’re a student who’s new to research papers or you’re preparing to write your dissertation , you might be wondering what the difference is between an abstract and an introduction.

Both serve important purposes in a research paper or journal article , but they shouldn’t be confused with each other. We’ve put together this guide to help you tell them apart.

What’s an Introduction?

In an academic context, an introduction is the first section of an essay or research paper. It should provide detailed background information about the study and its significance, as well as the researcher’s hypotheses and aims.

But the introduction shouldn’t discuss the study’s methods or results. There are separate sections for this later in the paper.

An introduction must correctly cite all sources used and should be about four paragraphs long, although the exact length depends on the topic and the style guide used.

What’s an Abstract?

While the introduction is the first section of a research paper, the abstract is a short summary of the entire paper. It should contain enough basic information to allow you to understand the content of the study without having to read the entire paper.

The abstract is especially important if the paper isn’t open access because it allows researchers to sift through many different studies before deciding which one to pay for.

Since the abstract contains only the essentials, it’s usually much shorter than an introduction and normally has a maximum word count of 200–300 words. It also doesn’t contain citations.

The exact layout of an abstract depends on whether it’s structured or unstructured. Unstructured abstracts are usually used in non-scientific disciplines, such as the arts and humanities, and usually consist of a single paragraph.

Structured abstracts, meanwhile, are the most common form of abstract used in scientific papers. They’re divided into different sections, each with its own heading. We’ll take a closer look at structured abstracts below.

Structuring an Abstract

A structured abstract contains concise information in a clear format with the following headings:

●  Background: Here you’ll find some relevant information about the topic being studied, such as why the study was necessary.

●  Objectives: This section is about the goals the researcher has for the study.

●  Methods: Here you’ll find a summary of how the study was conducted.

●  Results: Under this heading, the results of the study are presented.

●  Conclusions: The abstract ends with the researcher’s conclusions and how the study can inform future research.

Each of these sections, however, should contain less detail than the introduction or other sections of the main paper.

Abstract Vs. Introduction — Do you know the difference?

Ross wants to publish his research. Feeling positive about his research outcomes, he begins to draft his manuscript. After completing the abstract, he proceeds to write the introduction. That’s when he pauses in confusion. Do the abstract and introduction mean the same? How is the content for both the sections different?

This is a dilemma faced by several young researchers while drafting their first manuscript. An  abstract  is similar to a summary except that it is more concise and direct. Whereas, the  introduction  section of your paper is more detailed. It states why you conducted your study, what you wanted to accomplish, and what is your hypothesis.

This blog will allow us to learn more about the difference between the abstract and the introduction.

What Is an Abstract for a Research Paper?

An abstract provides the reader with a clear description of your research study and its results without the reader having to read the entire paper. The details of a study, such as precise methods and measurements, are not necessarily mentioned in the abstract. The abstract is an important tool for researchers who must sift through hundreds of papers from their field of study.

The abstract  holds more significance  in articles without open access. Reading the abstract would give an idea of the articles, which would otherwise require monetary payment for access. In most cases, reviewers will read the abstract to decide whether to continue to review the paper, which is important for you.

Your abstract should begin with a background or objective to clearly state why the research was done, its importance to the field of study, and any previous roadblocks encountered. It should include a very concise version of your methods, results, and conclusions but no references. It must be brief while still providing enough information so that the reader need not read the full article. Most journals ask that the abstract be no more than 200–250 words long.

Format of an Abstract

There are two general   formats — structured and unstructured. A  structured abstract   helps the reader find pertinent information  very quickly. It is divided into sections clearly defined by headings as follows:

• Background : Latest information on the topic; key phrases that pique interest (e.g., “…the role of this enzyme has never been clearly understood”).
• Objective : The research goals; what the study examined and why.
• Methods : Brief description of the study (e.g., retrospective study).
• Results : Findings and observations.
• Conclusions : Were these results expected? Whether more research is needed or not?

Authors get tempted to write too much  in an abstract but it is helpful to remember that there is usually a maximum word count. The main point is to relay the important aspects of the study without sharing too many details so that the readers do not have to go through the entire manuscript text for finding more information.

The  unstructured abstract  is often used in fields of study that do not fall under the category of science. This type of abstracts does not have different sections. It summarizes the manuscript’s objectives, methods, etc., in one paragraph.

Lastly, you must check the author guidelines of the target journal. It will describe the format required and the maximum word count of your abstract.

What Is an Introduction?

Your introduction is the first section of your research paper . It is not a repetition of the abstract. It does not provide data about methods, results, or conclusions. However, it  provides more in-depth information  on the background of the subject matter. It also explains your hypothesis , what you attempted to discover, or issues that you wanted to resolve. The introduction will also explain if and why your study is new in the subject field and why it is important.

It is often a good idea to wait until the rest of the paper is completed before drafting your introduction. This will help you to stay focused on the manuscript’s important points. The introduction, unlike the abstract, should contain citations to references. The information will help guide your readers through the rest of your document. The key tips for writing an effective introduction :

• Beginning:  The importance of the study.
• Tone/Tense:  Formal, impersonal; present tense.
• Content:  Brief description of manuscript but without results and conclusions.
• Length:  Generally up to four paragraphs. May vary slightly with journal guidelines.

Once you are sure that possible doubts on the difference between the abstract and introduction are clear, review and submit your manuscript.

Writing an Abstract for Your Research Paper

Definition and Purpose of Abstracts

An abstract is a short summary of your (published or unpublished) research paper, usually about a paragraph (c. 6-7 sentences, 150-250 words) long. A well-written abstract serves multiple purposes:

• an abstract lets readers get the gist or essence of your paper or article quickly, in order to decide whether to read the full paper;
• an abstract prepares readers to follow the detailed information, analyses, and arguments in your full paper;
• and, later, an abstract helps readers remember key points from your paper.

It’s also worth remembering that search engines and bibliographic databases use abstracts, as well as the title, to identify key terms for indexing your published paper. So what you include in your abstract and in your title are crucial for helping other researchers find your paper or article.

If you are writing an abstract for a course paper, your professor may give you specific guidelines for what to include and how to organize your abstract. Similarly, academic journals often have specific requirements for abstracts. So in addition to following the advice on this page, you should be sure to look for and follow any guidelines from the course or journal you’re writing for.

The Contents of an Abstract

Abstracts contain most of the following kinds of information in brief form. The body of your paper will, of course, develop and explain these ideas much more fully. As you will see in the samples below, the proportion of your abstract that you devote to each kind of information—and the sequence of that information—will vary, depending on the nature and genre of the paper that you are summarizing in your abstract. And in some cases, some of this information is implied, rather than stated explicitly. The Publication Manual of the American Psychological Association , which is widely used in the social sciences, gives specific guidelines for what to include in the abstract for different kinds of papers—for empirical studies, literature reviews or meta-analyses, theoretical papers, methodological papers, and case studies.

Here are the typical kinds of information found in most abstracts:

• the context or background information for your research; the general topic under study; the specific topic of your research
• the central questions or statement of the problem your research addresses
• what’s already known about this question, what previous research has done or shown
• the main reason(s) , the exigency, the rationale , the goals for your research—Why is it important to address these questions? Are you, for example, examining a new topic? Why is that topic worth examining? Are you filling a gap in previous research? Applying new methods to take a fresh look at existing ideas or data? Resolving a dispute within the literature in your field? . . .
• your research and/or analytical methods
• your main findings , results , or arguments
• the significance or implications of your findings or arguments.

Your abstract should be intelligible on its own, without a reader’s having to read your entire paper. And in an abstract, you usually do not cite references—most of your abstract will describe what you have studied in your research and what you have found and what you argue in your paper. In the body of your paper, you will cite the specific literature that informs your research.

When to Write Your Abstract

Although you might be tempted to write your abstract first because it will appear as the very first part of your paper, it’s a good idea to wait to write your abstract until after you’ve drafted your full paper, so that you know what you’re summarizing.

What follows are some sample abstracts in published papers or articles, all written by faculty at UW-Madison who come from a variety of disciplines. We have annotated these samples to help you see the work that these authors are doing within their abstracts.

Choosing Verb Tenses within Your Abstract

The social science sample (Sample 1) below uses the present tense to describe general facts and interpretations that have been and are currently true, including the prevailing explanation for the social phenomenon under study. That abstract also uses the present tense to describe the methods, the findings, the arguments, and the implications of the findings from their new research study. The authors use the past tense to describe previous research.

The humanities sample (Sample 2) below uses the past tense to describe completed events in the past (the texts created in the pulp fiction industry in the 1970s and 80s) and uses the present tense to describe what is happening in those texts, to explain the significance or meaning of those texts, and to describe the arguments presented in the article.

The science samples (Samples 3 and 4) below use the past tense to describe what previous research studies have done and the research the authors have conducted, the methods they have followed, and what they have found. In their rationale or justification for their research (what remains to be done), they use the present tense. They also use the present tense to introduce their study (in Sample 3, “Here we report . . .”) and to explain the significance of their study (In Sample 3, This reprogramming . . . “provides a scalable cell source for. . .”).

Sample Abstract 4, a Structured Abstract

Reporting results about the effectiveness of antibiotic therapy in managing acute bacterial sinusitis, from a rigorously controlled study

Note: This journal requires authors to organize their abstract into four specific sections, with strict word limits. Because the headings for this structured abstract are self-explanatory, we have chosen not to add annotations to this sample abstract.

Wald, Ellen R., David Nash, and Jens Eickhoff. “Effectiveness of Amoxicillin/Clavulanate Potassium in the Treatment of Acute Bacterial Sinusitis in Children.” Pediatrics , vol. 124, no. 1, 2009, pp. 9-15.

“OBJECTIVE: The role of antibiotic therapy in managing acute bacterial sinusitis (ABS) in children is controversial. The purpose of this study was to determine the effectiveness of high-dose amoxicillin/potassium clavulanate in the treatment of children diagnosed with ABS.

METHODS : This was a randomized, double-blind, placebo-controlled study. Children 1 to 10 years of age with a clinical presentation compatible with ABS were eligible for participation. Patients were stratified according to age (<6 or ≥6 years) and clinical severity and randomly assigned to receive either amoxicillin (90 mg/kg) with potassium clavulanate (6.4 mg/kg) or placebo. A symptom survey was performed on days 0, 1, 2, 3, 5, 7, 10, 20, and 30. Patients were examined on day 14. Children’s conditions were rated as cured, improved, or failed according to scoring rules.

RESULTS: Two thousand one hundred thirty-five children with respiratory complaints were screened for enrollment; 139 (6.5%) had ABS. Fifty-eight patients were enrolled, and 56 were randomly assigned. The mean age was 6630 months. Fifty (89%) patients presented with persistent symptoms, and 6 (11%) presented with nonpersistent symptoms. In 24 (43%) children, the illness was classified as mild, whereas in the remaining 32 (57%) children it was severe. Of the 28 children who received the antibiotic, 14 (50%) were cured, 4 (14%) were improved, 4(14%) experienced treatment failure, and 6 (21%) withdrew. Of the 28children who received placebo, 4 (14%) were cured, 5 (18%) improved, and 19 (68%) experienced treatment failure. Children receiving the antibiotic were more likely to be cured (50% vs 14%) and less likely to have treatment failure (14% vs 68%) than children receiving the placebo.

CONCLUSIONS : ABS is a common complication of viral upper respiratory infections. Amoxicillin/potassium clavulanate results in significantly more cures and fewer failures than placebo, according to parental report of time to resolution.” (9)

• How to Write an Abstract for a Dissertation or Thesis
• Doing a PhD

What is a Thesis or Dissertation Abstract?

The Cambridge English Dictionary defines an abstract in academic writing as being “ a few sentences that give the main ideas in an article or a scientific paper ” and the Collins English Dictionary says “ an abstract of an article, document, or speech is a short piece of writing that gives the main points of it ”.

Whether you’re writing up your Master’s dissertation or PhD thesis, the abstract will be a key element of this document that you’ll want to make sure you give proper attention to.

What is the Purpose of an Abstract?

The aim of a thesis abstract is to give the reader a broad overview of what your research project was about and what you found that was novel, before he or she decides to read the entire thesis. The reality here though is that very few people will read the entire thesis, and not because they’re necessarily disinterested but because practically it’s too large a document for most people to have the time to read. The exception to this is your PhD examiner, however know that even they may not read the entire length of the document.

Some people may still skip to and read specific sections throughout your thesis such as the methodology, but the fact is that the abstract will be all that most read and will therefore be the section they base their opinions about your research on. In short, make sure you write a good, well-structured abstract.

How Long Should an Abstract Be?

If you’re a PhD student, having written your 100,000-word thesis, the abstract will be the 300 word summary included at the start of the thesis that succinctly explains the motivation for your study (i.e. why this research was needed), the main work you did (i.e. the focus of each chapter), what you found (the results) and concluding with how your research study contributed to new knowledge within your field.

Woodrow Wilson, the 28th President of the United States of America, once famously said:

The point here is that it’s easier to talk open-endedly about a subject that you know a lot about than it is to condense the key points into a 10-minute speech; the same applies for an abstract. Three hundred words is not a lot of words which makes it even more difficult to condense three (or more) years of research into a coherent, interesting story.

What Makes a Good PhD Thesis Abstract?

Whilst the abstract is one of the first sections in your PhD thesis, practically it’s probably the last aspect that you’ll ending up writing before sending the document to print. The reason being that you can’t write a summary about what you did, what you found and what it means until you’ve done the work.

A good abstract is one that can clearly explain to the reader in 300 words:

• What your research field actually is,
• What the gap in knowledge was in your field,
• The overarching aim and objectives of your PhD in response to these gaps,
• What methods you employed to achieve these,
• You key results and findings,
• How your work has added to further knowledge in your field of study.

Another way to think of this structure is:

• Introduction,
• Aims and objectives,
• Discussion,
• Conclusion.

Following this ‘formulaic’ approach to writing the abstract should hopefully make it a little easier to write but you can already see here that there’s a lot of information to convey in a very limited number of words.

How Do You Write a Good PhD Thesis Abstract?

The biggest challenge you’ll have is getting all the 6 points mentioned above across in your abstract within the limit of 300 words . Your particular university may give some leeway in going a few words over this but it’s good practice to keep within this; the art of succinctly getting your information across is an important skill for a researcher to have and one that you’ll be called on to use regularly as you write papers for peer review.

Keep It Concise

Every word in the abstract is important so make sure you focus on only the key elements of your research and the main outcomes and significance of your project that you want the reader to know about. You may have come across incidental findings during your research which could be interesting to discuss but this should not happen in the abstract as you simply don’t have enough words. Furthermore, make sure everything you talk about in your thesis is actually described in the main thesis.

Make a Unique Point Each Sentence

Keep the sentences short and to the point. Each sentence should give the reader new, useful information about your research so there’s no need to write out your project title again. Give yourself one or two sentences to introduce your subject area and set the context for your project. Then another sentence or two to explain the gap in the knowledge; there’s no need or expectation for you to include references in the abstract.

Explain Your Research

Some people prefer to write their overarching aim whilst others set out their research questions as they correspond to the structure of their thesis chapters; the approach you use is up to you, as long as the reader can understand what your dissertation or thesis had set out to achieve. Knowing this will help the reader better understand if your results help to answer the research questions or if further work is needed.

Keep It Factual

Keep the content of the abstract factual; that is to say that you should avoid bringing too much or any opinion into it, which inevitably can make the writing seem vague in the points you’re trying to get across and even lacking in structure.

Write, Edit and Then Rewrite

Spend suitable time editing your text, and if necessary, completely re-writing it. Show the abstract to others and ask them to explain what they understand about your research – are they able to explain back to you each of the 6 structure points, including why your project was needed, the research questions and results, and the impact it had on your research field? It’s important that you’re able to convey what new knowledge you contributed to your field but be mindful when writing your abstract that you don’t inadvertently overstate the conclusions, impact and significance of your work.

Thesis and Dissertation Abstract Examples

Perhaps the best way to understand how to write a thesis abstract is to look at examples of what makes a good and bad abstract.

Example of A Bad Abstract

Let’s start with an example of a bad thesis abstract:

In this project on “The Analysis of the Structural Integrity of 3D Printed Polymers for use in Aircraft”, my research looked at how 3D printing of materials can help the aviation industry in the manufacture of planes. Plane parts can be made at a lower cost using 3D printing and made lighter than traditional components. This project investigated the structural integrity of EBM manufactured components, which could revolutionise the aviation industry.

What Makes This a Bad Abstract

Hopefully you’ll have spotted some of the reasons this would be considered a poor abstract, not least because the author used up valuable words by repeating the lengthy title of the project in the abstract.

Working through our checklist of the 6 key points you want to convey to the reader:

• There has been an attempt to introduce the research area , albeit half-way through the abstract but it’s not clear if this is a materials science project about 3D printing or is it about aircraft design.
• There’s no explanation about where the gap in the knowledge is that this project attempted to address.
• We can see that this project was focussed on the topic of structural integrity of materials in aircraft but the actual research aims or objectives haven’t been defined.
• There’s no mention at all of what the author actually did to investigate structural integrity. For example was this an experimental study involving real aircraft, or something in the lab, computer simulations etc.
• The author also doesn’t tell us a single result of his research, let alone the key findings !
• There’s a bold claim in the last sentence of the abstract that this project could revolutionise the aviation industry, and this may well be the case, but based on the abstract alone there is no evidence to support this as it’s not even clear what the author did .

This is an extreme example but is a good way to illustrate just how unhelpful a poorly written abstract can be. At only 71 words long, it definitely hasn’t maximised the amount of information that could be presented and the what they have presented has lacked clarity and structure.

A final point to note is the use of the EBM acronym, which stands for Electron Beam Melting in the context of 3D printing; this is a niche acronym for the author to assume that the reader would know the meaning of. It’s best to avoid acronyms in your abstract all together even if it’s something that you might expect most people to know about, unless you specifically define the meaning first.

Example of A Good Abstract

Having seen an example of a bad thesis abstract, now lets look at an example of a good PhD thesis abstract written about the same (fictional) project:

Additive manufacturing (AM) of titanium alloys has the potential to enable cheaper and lighter components to be produced with customised designs for use in aircraft engines. Whilst the proof-of-concept of these have been promising, the structural integrity of AM engine parts in response to full thrust and temperature variations is not clear.

The primary aim of this project was to determine the fracture modes and mechanisms of AM components designed for use in Boeing 747 engines. To achieve this an explicit finite element (FE) model was developed to simulate the environment and parameters that the engine is exposed to during flight. The FE model was validated using experimental data replicating the environmental parameters in a laboratory setting using ten AM engine components provided by the industry sponsor. The validated FE model was then used to investigate the extent of crack initiation and propagation as the environment parameters were adjusted.

This project was the first to investigate fracture patterns in AM titanium components used in aircraft engines; the key finding was that the presence of cavities within the structures due to errors in the printing process, significantly increased the risk of fracture. Secondly, the simulations showed that cracks formed within AM parts were more likely to worsen and lead to component failure at subzero temperatures when compared to conventionally manufactured parts. This has demonstrated an important safety concern which needs to be addressed before AM parts can be used in commercial aircraft.

What Makes This a Good Abstract

Having read this ‘good abstract’ you should have a much better understand about what the subject area is about, where the gap in the knowledge was, the aim of the project, the methods that were used, key results and finally the significance of these results. To break these points down further, from this good abstract we now know that:

• The research area is around additive manufacturing (i.e. 3D printing) of materials for use in aircraft.
• The gap in knowledge was how these materials will behave structural when used in aircraft engines.
• The aim was specifically to investigate how the components can fracture.
• The methods used to investigate this were a combination of computational and lab based experimental modelling.
• The key findings were the increased risk of fracture of these components due to the way they are manufactured.
• The significance of these findings were that it showed a potential risk of component failure that could comprise the safety of passengers and crew on the aircraft.

The abstract text has a much clearer flow through these different points in how it’s written and has made much better use of the available word count. Acronyms have even been used twice in this good abstract but they were clearly defined the first time they were introduced in the text so that there was no confusion about their meaning.

The abstract you write for your dissertation or thesis should succinctly explain to the reader why the work of your research was needed, what you did, what you found and what it means. Most people that come across your thesis, including any future employers, are likely to read only your abstract. Even just for this reason alone, it’s so important that you write the best abstract you can; this will not only convey your research effectively but also put you in the best light possible as a researcher.

• Key Differences

Know the Differences & Comparisons

Difference Between Abstract and Introduction

On the other hand, the abstract is like a short summary of an academic article or research paper, which discusses the purpose of the study and the outcome of the research. It usually summarizes the research topic, questions, participants, methods, outcome, data collected, analysis and conclusions. The article excerpt given hereunder discusses the difference between abstract and introduction.

Content: Abstract Vs Introduction

Comparison chart, definition of abstract.

An abstract can be described as a concise summary, often found in research work like thesis, dissertations, research articles, review, etc. which helps the reader to have an instant idea of the main purpose of the work. It is about a paragraph long of 150 to 250 words in general.

The information contained in the abstract should be sufficient enough to help the readers judge the nature and importance of the topic, the reasonableness of the strategy used in the investigation, nature of results and conclusions.

An abstract serves a number of purposes such as it allows the readers to get the gist of your paper, so as to decide whether to go through with the rest of the work. It is usually written after the writing of the paperwork is over and that too in the past tense.

An abstract rolls all the important information of the work into a single page, such as the context, general topic, central questions, problem under study, main idea, previous research findings, reasons, research methodology, findings, results, arguments, implications, conclusion and so on. To create an abstract one should pick the main statements from the above-mentioned sections, to draft an abstract.

Types of Abstract

• Descriptive Abstract : It briefly describes the abstract and the length is usually 100-200 words. It indicates the type of information contained in the paper, discusses the purpose of writing, objectives and methods used for research.
• Informative Abstract : As the name suggests, it is a detailed abstract which summarizes all the important points of the study. It includes results and conclusions, along with the purpose, objective, and methods used.

Definition of Introduction

Introduction means to present something to the readers, i.e. by giving a brief description or background information of the document. It is the first and foremost section which expresses the purpose, scope and goals, concerning the topic under study. As an introduction gives an overview of the topic, it develops an understanding of the main text.

An introduction is a gateway to the topic, as it is something which can create interest in the readers to read the document further. It is the crux of the document, which states what is to be discussed in the main body.

Elements of Introduction

An introduction has four basic elements namely: hook, background information, connect and thesis statement.

• Hook is the preliminary sentence of the introduction which is used to fasten the attention of the readers, and so it has to be interesting, attention-grabbing, and readable of course, so as to stimulate the readers to read the complete text.
• Background Information is the main part of the introduction, which presents the background of the research topic, including the problem under study, real-world situation, research questions, and a sneak peek of what the readers can expect from the main body.
• Connect , is a simple line which is used to link or say relate the background information with the research statement, by using words ideas or phrases, so as to ensure the flow and logic of writing the text.
• Thesis statement is the central point of the argument, which is usually a single sentence, whose points of evidence are to be talked about in the following text, i.e. the main body.

Key Differences Between Abstract and Introduction

The difference between abstract and introduction are discussed in the points:

• An abstract is a concise and accurate representation which gives an overview of the main points from the entire document. On the other hand, Introduction is the first section which makes the reader aware of the subject, by giving a brief description of the work, i.e. why the research is needed or important.
• While an abstract will give you an immediate overview of the paper, the introduction is the initial exposure to the subject under study.
• An abstract reports key points of the research, as well as it states why the work is important, what was the main purpose of research, what is the motivation behind choosing the subject, what you learned from the research, what you found out during the research and what you concluded, in a summarized way. As against, an introduction presents a direction to understand what exists in the upcoming portion of the document or book.
• As an abstract has its own introduction, main body and conclusion, it is a standalone document which summarizes the result of the findings and not just the list of topics discussed. As against, the introduction is not a standalone document or piece.
• The main purpose of an abstract is to provide a succinct summary of the research. Conversely, introduction aims at convincing the reader about the need for the research.
• An abstract contains the purpose, problem, methods used, result and conclusion. On the contrary, the introduction includes a hook, background information, connect and thesis statement.
• While abstract is found in a research paper, thesis and dissertations, the introduction is found in a wide range of texts.

An abstract gives a preview of the work, outlines the main points and helps the audience in decision making, i.e. whether they want to read the complete text or not. On the other hand, an introduction is the very first section of the work, which clarifies the purpose of writing.

Without an abstract and introduction, the readers might not be able to know what the work contains and what is the reason or motivation behind the research. So, these two are like thread which goes through the writing and creates an understanding in the reader about the topic under study. While writing these two, one should ensure that they accurately reflect what you cover in the document or book.

How to write a fantastic thesis introduction (+15 examples)

The thesis introduction, usually chapter 1, is one of the most important chapters of a thesis. It sets the scene. It previews key arguments and findings. And it helps the reader to understand the structure of the thesis. In short, a lot is riding on this first chapter. With the following tips, you can write a powerful thesis introduction.

Elements of a fantastic thesis introduction

Open with a (personal) story, begin with a problem, define a clear research gap, describe the scientific relevance of the thesis, describe the societal relevance of the thesis, write down the thesis’ core claim in 1-2 sentences, support your argument with sufficient evidence, consider possible objections, address the empirical research context, give a taste of the thesis’ empirical analysis, hint at the practical implications of the research, provide a reading guide, briefly summarise all chapters to come, design a figure illustrating the thesis structure.

An introductory chapter plays an integral part in every thesis. The first chapter has to include quite a lot of information to contextualise the research. At the same time, a good thesis introduction is not too long, but clear and to the point.

A powerful thesis introduction does the following:

• It captures the reader’s attention.
• It presents a clear research gap and emphasises the thesis’ relevance.
• It provides a compelling argument.
• It previews the research findings.
• It explains the structure of the thesis.

In addition, a powerful thesis introduction is well-written, logically structured, and free of grammar and spelling errors. Reputable thesis editors can elevate the quality of your introduction to the next level. If you are in search of a trustworthy thesis or dissertation editor who upholds high-quality standards and offers efficient turnaround times, I recommend the professional thesis and dissertation editing service provided by Editage . 

This list can feel quite overwhelming. However, with some easy tips and tricks, you can accomplish all these goals in your thesis introduction. (And if you struggle with finding the right wording, have a look at academic key phrases for introductions .)

Ways to capture the reader’s attention

A powerful thesis introduction should spark the reader’s interest on the first pages. A reader should be enticed to continue reading! There are three common ways to capture the reader’s attention.

An established way to capture the reader’s attention in a thesis introduction is by starting with a story. Regardless of how abstract and ‘scientific’ the actual thesis content is, it can be useful to ease the reader into the topic with a short story.

This story can be, for instance, based on one of your study participants. It can also be a very personal account of one of your own experiences, which drew you to study the thesis topic in the first place.

Start by providing data or statistics

Data and statistics are another established way to immediately draw in your reader. Especially surprising or shocking numbers can highlight the importance of a thesis topic in the first few sentences!

So if your thesis topic lends itself to being kick-started with data or statistics, you are in for a quick and easy way to write a memorable thesis introduction.

The third established way to capture the reader’s attention is by starting with the problem that underlies your thesis. It is advisable to keep the problem simple. A few sentences at the start of the chapter should suffice.

Usually, at a later stage in the introductory chapter, it is common to go more in-depth, describing the research problem (and its scientific and societal relevance) in more detail.

Emphasising the thesis’ relevance

A good thesis is a relevant thesis. No one wants to read about a concept that has already been explored hundreds of times, or that no one cares about.

Of course, a thesis heavily relies on the work of other scholars. However, each thesis is – and should be – unique. If you want to write a fantastic thesis introduction, your job is to point out this uniqueness!

In academic research, a research gap signifies a research area or research question that has not been explored yet, that has been insufficiently explored, or whose insights and findings are outdated.

Every thesis needs a crystal-clear research gap. Spell it out instead of letting your reader figure out why your thesis is relevant.

* This example has been taken from an actual academic paper on toxic behaviour in online games: Liu, J. and Agur, C. (2022). “After All, They Don’t Know Me” Exploring the Psychological Mechanisms of Toxic Behavior in Online Games. Games and Culture 1–24, DOI: 10.1177/15554120221115397

The scientific relevance of a thesis highlights the importance of your work in terms of advancing theoretical insights on a topic. You can think of this part as your contribution to the (international) academic literature.

Scientific relevance comes in different forms. For instance, you can critically assess a prominent theory explaining a specific phenomenon. Maybe something is missing? Or you can develop a novel framework that combines different frameworks used by other scholars. Or you can draw attention to the context-specific nature of a phenomenon that is discussed in the international literature.

The societal relevance of a thesis highlights the importance of your research in more practical terms. You can think of this part as your contribution beyond theoretical insights and academic publications.

Why are your insights useful? Who can benefit from your insights? How can your insights improve existing practices?

Formulating a compelling argument

Arguments are sets of reasons supporting an idea, which – in academia – often integrate theoretical and empirical insights. Think of an argument as an umbrella statement, or core claim. It should be no longer than one or two sentences.

Including an argument in the introduction of your thesis may seem counterintuitive. After all, the reader will be introduced to your core claim before reading all the chapters of your thesis that led you to this claim in the first place.

But rest assured: A clear argument at the start of your thesis introduction is a sign of a good thesis. It works like a movie teaser to generate interest. And it helps the reader to follow your subsequent line of argumentation.

The core claim of your thesis should be accompanied by sufficient evidence. This does not mean that you have to write 10 pages about your results at this point.

However, you do need to show the reader that your claim is credible and legitimate because of the work you have done.

A good argument already anticipates possible objections. Not everyone will agree with your core claim. Therefore, it is smart to think ahead. What criticism can you expect?

Think about reasons or opposing positions that people can come up with to disagree with your claim. Then, try to address them head-on.

Providing a captivating preview of findings

Similar to presenting a compelling argument, a fantastic thesis introduction also previews some of the findings. When reading an introduction, the reader wants to learn a bit more about the research context. Furthermore, a reader should get a taste of the type of analysis that will be conducted. And lastly, a hint at the practical implications of the findings encourages the reader to read until the end.

If you focus on a specific empirical context, make sure to provide some information about it. The empirical context could be, for instance, a country, an island, a school or city. Make sure the reader understands why you chose this context for your research, and why it fits to your research objective.

If you did all your research in a lab, this section is obviously irrelevant. However, in that case you should explain the setup of your experiment, etcetera.

The empirical part of your thesis centers around the collection and analysis of information. What information, and what evidence, did you generate? And what are some of the key findings?

For instance, you can provide a short summary of the different research methods that you used to collect data. Followed by a short overview of how you analysed this data, and some of the key findings. The reader needs to understand why your empirical analysis is worth reading.

You already highlighted the practical relevance of your thesis in the introductory chapter. However, you should also provide a preview of some of the practical implications that you will develop in your thesis based on your findings.

Presenting a crystal clear thesis structure

A fantastic thesis introduction helps the reader to understand the structure and logic of your whole thesis. This is probably the easiest part to write in a thesis introduction. However, this part can be best written at the very end, once everything else is ready.

A reading guide is an essential part in a thesis introduction! Usually, the reading guide can be found toward the end of the introductory chapter.

The reading guide basically tells the reader what to expect in the chapters to come.

In a longer thesis, such as a PhD thesis, it can be smart to provide a summary of each chapter to come. Think of a paragraph for each chapter, almost in the form of an abstract.

For shorter theses, which also have a shorter introduction, this step is not necessary.

Especially for longer theses, it tends to be a good idea to design a simple figure that illustrates the structure of your thesis. It helps the reader to better grasp the logic of your thesis.

Many of the components following the title and copyright pages have required headings and formatting guidelines, which are described in the following sections.

Please consult the Sample Pages to compare your document to the requirements. A Checklist is provided to assist you in ensuring your thesis or dissertation meets all formatting guidelines.

The title page of a thesis or dissertation must include the following information:

• The title of the thesis or dissertation in all capital letters and centered 2″ below the top of the page.
• Your name, centered 1″ below the title. Do not include titles, degrees, or identifiers. The name you use here does not need to exactly match the name on your university records, but we recommend considering how you will want your name to appear in professional publications in the future.

Notes on this statement:

• When indicating your degree in the second bracketed space, use the full degree name (i.e., Doctor of Philosophy, not Ph.D. or PHD; Master of Public Health, not M.P.H. or MPH; Master of Social Work, not M.S.W. or MSW).
• List your department, school, or curriculum rather than your subject area or specialty discipline in the third bracketed space. You may include your subject area or specialty discipline in parentheses (i.e., Department of Romance Languages (French); School of Pharmacy (Molecular Pharmaceutics); School of Education (School Psychology); or similar official area).
• If you wish to include both your department and school names, list the school at the end of the statement (i.e., Department of Pharmacology in the School of Medicine).
• A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Public Policy.

• A dissertation submitted to the faculty at the University of North Carolina at Chapel Hill in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the School of Education (Cultural Studies and Literacies).
• The words “Chapel Hill” must be centered 1″ below the statement.
• One single-spaced line below that, center the year in which your committee approves the completed thesis or dissertation. This need not be the year you graduate.
• Approximately 2/3 of the way across the page on the right-hand side of the page, 1″ below the year, include the phrase “Approved by:” (with colon) followed by each faculty member's name on subsequent double-spaced lines. Do not include titles such as Professor, Doctor, Dr., PhD, or any identifiers such as “chair” or “advisor” before or after any names. Line up the first letter of each name on the left under the “A” in the “Approved by:” line. If a name is too long to fit on one line, move this entire section of text slightly to the left so that formatting can be maintained.
• No signatures, signature lines, or page numbers should be included on the title page.

Include a copyright page with the following information single-spaced and centered 2″ above the bottom of the page:

© Year Author's Full Name (as it appears on the title page) ALL RIGHTS RESERVED

This page immediately follows the title page. It should be numbered with the lower case Roman numeral ii centered with a 1/2″ margin from the bottom edge.

Inclusion of this page offers you, as the author, additional protection against copyright infringement as it eliminates any question of authorship and copyright ownership. You do not need to file for copyright in order to include this statement in your thesis or dissertation. However, filing for copyright can offer other protections.

See Section IV for more information on copyrighting your thesis or dissertation.

Include an abstract page following these guidelines:

• Include the heading “ABSTRACT” in all capital letters, and center it 2″ below the top of the page.
• One double-spaced line below “ABSTRACT”, center your name, followed by a colon and the title of the thesis or dissertation. Use as many lines as necessary. Be sure that your name and the title exactly match the name and title used on the Title page.
• One single-spaced line below the title, center the phrase “(Under the direction of [advisor's name])”. Include the phrase in parentheses. Include the first and last name(s) of your advisor or formal co-advisors. Do not include the name of other committee members. Use the advisor's name only; do not include any professional titles such as PhD, Professor, or Dr. or any identifiers such as “chair” or “advisor”.
• Skip one double-spaced line and begin the abstract. The text of your abstract must be double-spaced and aligned with the document's left margin with the exception of indenting new paragraphs. Do not center or right-justify the abstract.
• Abstracts cannot exceed 150 words for a thesis or 350 words for a dissertation.
• Number the abstract page with the lower case Roman numeral iii (and iv, if more than one page) centered with a 1/2″ margin from the bottom edge.

Please write and proofread your abstract carefully. When possible, avoid including symbols or foreign words in your abstract, as they cannot be indexed or searched. Avoid mathematical formulas, diagrams, and other illustrative materials in the abstract. Offer a brief description of your thesis or dissertation and a concise summary of its conclusions. Be sure to describe the subject and focus of your work with clear details and avoid including lengthy explanations or opinions.

Your title and abstract will be used by search engines to help potential audiences locate your work, so clarity will help to draw the attention of your targeted readers.

You have an option to include a dedication, acknowledgements, or preface. If you choose to include any or all of these elements, give each its own page(s).

A dedication is a message from the author prefixed to a work in tribute to a person, group, or cause. Most dedications are short statements of tribute beginning with “To…” such as “To my family”.

Acknowledgements are the author's statement of gratitude to and recognition of the people and institutions that helped the author's research and writing.

A preface is a statement of the author's reasons for undertaking the work and other personal comments that are not directly germane to the materials presented in other sections of the thesis or dissertation. These reasons tend to be of a personal nature.

Any of the pages must be prepared following these guidelines:

• Do not place a heading on the dedication page.
• The text of short dedications must be centered and begin 2″ from the top of the page.
• Headings are required for the “ACKNOWLEDGEMENTS” and “PREFACE” pages. Headings must be in all capital letters and centered 2″ below the top of the page.
• The text of the acknowledgements and preface pages must begin one double-spaced line below the heading, be double-spaced, and be aligned with the document's left margin with the exception of indenting new paragraphs.
• Subsequent pages of text return to the 1″ top margin.
• The page(s) must be numbered with consecutive lower case Roman numerals (starting with the page number after the abstract) centered with a 1/2″ margin from the bottom edge.

Include a table of contents following these guidelines:

• Assign each table, figure, or illustration in your thesis or dissertation an Arabic numeral. You may number consecutively throughout the entire work (e.g., Figure 1, Figure 2, etc.), or you may assign a two-part Arabic numeral with the first number designating the chapter in which it appears, separated by a period, followed by a second number to indicate its consecutive placement in the chapter (e.g., Table 3.2 is the second table in Chapter Three).
• Numerals and titles must align with the document's left margin or be indented to the right of the left page margin using consistent tabs.
• Page numbers must be located just inside the right page margin with leaders (lines of periods) filling out the space between the end of the entry and the page number. The last digit of each number must line up on the right margin.

Frequently asked questions

Where does my abstract go in a thesis or dissertation.

The abstract appears on its own page, after the title page and acknowledgements but before the table of contents .

Frequently asked questions: Dissertation

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

The best way to remember the difference between a research plan and a research proposal is that they have fundamentally different audiences. A research plan helps you, the researcher, organize your thoughts. On the other hand, a dissertation proposal or research proposal aims to convince others (e.g., a supervisor, a funding body, or a dissertation committee) that your research topic is relevant and worthy of being conducted.

Formulating a main research question can be a difficult task. Overall, your question should contribute to solving the problem that you have defined in your problem statement .

However, it should also fulfill criteria in three main areas:

• Researchability
• Feasibility and specificity
• Relevance and originality

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

Results are usually written in the past tense , because they are describing the outcome of completed actions.

Avoid citing sources in your abstract . There are two reasons for this:

• The abstract should focus on your original research, not on the work of others.
• The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis or paper.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

• To help potential readers determine the relevance of your paper for their own research.
• To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarises the contents of your paper.

A theoretical framework can sometimes be integrated into a  literature review chapter , but it can also be included as its own chapter or section in your dissertation . As a rule of thumb, if your research involves dealing with a lot of complex theories, it’s a good idea to include a separate theoretical framework chapter.

A literature review and a theoretical framework are not the same thing and cannot be used interchangeably. While a theoretical framework describes the theoretical underpinnings of your work, a literature review critically evaluates existing research relating to your topic. You’ll likely need both in your dissertation .

While a theoretical framework describes the theoretical underpinnings of your work based on existing research, a conceptual framework allows you to draw your own conclusions, mapping out the variables you may use in your study and the interplay between them.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organise your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation, such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review, research methods, avenues for future research, etc.)

Your list of tables and figures should go directly after your table of contents in your thesis or dissertation.

Usually, no title page is needed in an MLA paper . A header is generally included at the top of the first page instead. The exceptions are when:

• Your instructor requires one, or
• Your paper is a group project

In those cases, you should use a title page instead of a header, listing the same information but on a separate page.

The title page of your thesis or dissertation goes first, before all other content or lists that you may choose to include.

The title page of your thesis or dissertation should include your name, department, institution, degree program, and submission date.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, dictionaries are more general collections of words.

Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one to your thesis or dissertation. Your educational institution may also require them, so be sure to check their specific guidelines.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, an index is a list of the contents of your work organised by page number.

Definitional terms often fall into the category of common knowledge , meaning that they don’t necessarily have to be cited. This guidance can apply to your thesis or dissertation glossary as well.

However, if you’d prefer to cite your sources , you can follow guidance for citing dictionary entries in MLA or APA style for your glossary.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. Your glossary only needs to include terms that your reader may not be familiar with, and is intended to enhance their understanding of your work.

APA doesn’t require you to include a list of tables or a list of figures . However, it is advisable to do so if your text is long enough to feature a table of contents and it includes a lot of tables and/or figures .

A list of tables and list of figures appear (in that order) after your table of contents, and are presented in a similar way.

A list of figures and tables compiles all of the figures and tables that you used in your thesis or dissertation and displays them with the page number where they can be found.

Copyright information can usually be found wherever the table or figure was published. For example, for a diagram in a journal article , look on the journal’s website or the database where you found the article. Images found on sites like Flickr are listed with clear copyright information.

If you find that permission is required to reproduce the material, be sure to contact the author or publisher and ask for it.

Lists of figures and tables are often not required, and they aren’t particularly common. They specifically aren’t required for APA Style, though you should be careful to follow their other guidelines for figures and tables .

If you have many figures and tables in your thesis or dissertation, include one may help you stay organised. Your educational institution may require them, so be sure to check their guidelines.

Yes, if your document is longer than 20,000 words, you will get a sample of approximately 2,000 words. This sample edit gives you a first impression of the editor’s editing style and a chance to ask questions and give feedback.

How does the sample edit work?

You will receive the sample edit within 24 hours after placing your order. You then have 24 hours to let us know if you’re happy with the sample or if there’s something you would like the editor to do differently.

Yes, you can upload your document in sections.

We try our best to ensure that the same editor checks all the different sections of your document. When you upload a new file, our system recognizes you as a returning customer, and we immediately contact the editor who helped you before.

However, we cannot guarantee that the same editor will be available. Your chances are higher if

• You send us your text as soon as possible and
• You can be flexible about the deadline.

Please note that the shorter your deadline is, the lower the chance that your previous editor is not available.

If your previous editor isn’t available, then we will inform you immediately and look for another qualified editor. Fear not! Every Scribbr editor follows the  Scribbr Improvement Model  and will deliver high-quality work.

Yes, our editors also work during the weekends and holidays.

Because we have many editors available, we can check your document 24 hours per day and 7 days per week, all year round.

If you choose a 72 hour deadline and upload your document on a Thursday evening, you’ll have your thesis back by Sunday evening!

Yes! Our editors are all native speakers, and they have lots of experience editing texts written by ESL students. They will make sure your grammar is perfect and point out any sentences that are difficult to understand. They’ll also notice your most common mistakes, and give you personal feedback to improve your writing in English.

Every Scribbr order comes with our award-winning Proofreading & Editing service , which combines two important stages of the revision process.

For a more comprehensive edit, you can add a Structure Check or Clarity Check to your order. With these building blocks, you can customize the kind of feedback you receive.

You might be familiar with a different set of editing terms. To help you understand what you can expect at Scribbr, we created this table:

When you place an order, you can specify your field of study and we’ll match you with an editor who has familiarity with this area.

However, our editors are language specialists, not academic experts in your field. Your editor’s job is not to comment on the content of your dissertation, but to improve your language and help you express your ideas as clearly and fluently as possible.

This means that your editor will understand your text well enough to give feedback on its clarity, logic and structure, but not on the accuracy or originality of its content.

Good academic writing should be understandable to a non-expert reader, and we believe that academic editing is a discipline in itself. The research, ideas and arguments are all yours – we’re here to make sure they shine!

After your document has been edited, you will receive an email with a link to download the document.

The editor has made changes to your document using ‘Track Changes’ in Word. This means that you only have to accept or ignore the changes that are made in the text one by one.

It is also possible to accept all changes at once. However, we strongly advise you not to do so for the following reasons:

• You can learn a lot by looking at the mistakes you made.
• The editors don’t only change the text – they also place comments when sentences or sometimes even entire paragraphs are unclear. You should read through these comments and take into account your editor’s tips and suggestions.
• With a final read-through, you can make sure you’re 100% happy with your text before you submit!

You choose the turnaround time when ordering. We can return your dissertation within 24 hours , 3 days or 1 week . These timescales include weekends and holidays. As soon as you’ve paid, the deadline is set, and we guarantee to meet it! We’ll notify you by text and email when your editor has completed the job.

Very large orders might not be possible to complete in 24 hours. On average, our editors can complete around 13,000 words in a day while maintaining our high quality standards. If your order is longer than this and urgent, contact us to discuss possibilities.

Always leave yourself enough time to check through the document and accept the changes before your submission deadline.
