EBSCO Open Dissertations

EBSCO Open Dissertations makes electronic theses and dissertations (ETDs) more accessible to researchers worldwide. The free portal is designed to benefit universities and their students and make ETDs more discoverable. 

Increasing Discovery & Usage of ETD Research

EBSCO Open Dissertations is a collaboration between EBSCO and BiblioLabs to increase traffic and discoverability of ETD research. You can join the movement and add your theses and dissertations to the database, making them freely available to researchers everywhere while increasing traffic to your institutional repository. 

EBSCO Open Dissertations extends the work started in 2014, when EBSCO and the H.W. Wilson Foundation created American Doctoral Dissertations which contained indexing from the H.W. Wilson print publication, Doctoral Dissertations Accepted by American Universities, 1933-1955. In 2015, the H.W. Wilson Foundation agreed to support the expansion of the scope of the American Doctoral Dissertations database to include records for dissertations and theses from 1955 to the present.

How Does EBSCO Open Dissertations Work?

Your ETD metadata is harvested via OAI and integrated into EBSCO’s platform, where pointers send traffic to your IR.

EBSCO integrates this data into their current subscriber environments and makes the data available on the open web via opendissertations.org .

UVA's newly-renovated main library, Shannon, is open! As we move the books back in, services may be impacted. See current service status.

Electronic theses & dissertations (ETDs)

Electronic dissertations and masters’ theses have been deposited in the Libra scholarly repository at the University of Virginia since 2012. Libra makes UVA scholarship available to the world and provides safe and secure storage for the scholarly output of the UVA community. Submitting your work to Libra is a graduation requirement for all graduate students whose programs have required theses and for PhD students. LibraETD is can be used by all students, undergraduate  or graduate, whose programs have optional theses or capstones.

Before you upload your thesis or dissertation, be sure you have reviewed:

Copyright Essentials for Scholarly Work  (including Graduate Students)

The ETD Submission Checklist

Older dissertation formats

All dissertations submitted to the UVA Library in CD format were deposited into Libra in early 2014. Access to these items is UVA-only, replicating the accessibility level of the originally deposited CDs.

If you are the author of one of these dissertations and would like to change the access level to be world-wide open access, please  contact us .

Paper copies

We no longer accept paper copies for the Library shelves.  Many frequently requested dissertations from the UVA collection have been added to Libra through a generous grant from Jefferson Trust. If you are the author of one of these dissertations now in Libra and would like to change the access level to be world-wide open access, please  contact us .

If your dissertation was published in paper previously and you would like it to be added to Libra, please  contact us .

Many UVA dissertations were deposited in ProQuest until 2012, and some students continue to take the option to deposit to this commercial vendor of databases and other information products. ProQuest’s  Dissertations and Theses Full Text  database contains many dissertations published in the U.S. and is used by scholars worldwide whose institutions opt to provide paid access to the database. ProQuest also sells full-text copies of dissertations directly to the public, though it is worth noting they do not share revenue from those sales with authors. NOTE: To access "online" ETD's in Proquest, you must be affiliated with an institution that subscribes to the ProQuest database.

ProQuest charges fees for submission, and they have particular formatting and copyright requirements.  Please see their  submission instructions  for details. UVA does not require thesis or dissertation deposit to ProQuest, nor does UVA have an institutional agreement with ProQuest for such deposit. Students who opt to deposit with ProQuest do so as individuals contracting with this vendor.

Growing our donated organ supply

Press contact :.

Previous image Next image

For those in need of one, an organ transplant is a matter of life and death. 

Every year, the medical procedure gives thousands of people with advanced or end-stage diseases extended life. This “second chance” is heavily dependent on the availability, compatibility, and proximity of a precious resource that can’t be simply bought, grown, or manufactured — at least not yet.

Instead, organs must be given — cut from one body and implanted into another. And because living organ donation is only viable in certain cases, many organs are only available for donation after the donor’s death.

Unsurprisingly, the logistical and ethical complexity of distributing a limited number of transplant organs to a growing wait list of patients has received much attention. There’s an important part of the process that has received less focus, however, and which may hold significant untapped potential: organ procurement itself.

“If you have a donated organ, who should you give it to? This question has been extensively studied in operations research, economics, and even applied computer science,” says Hammaad Adam , a graduate student in the Social and Engineering Systems (SES) doctoral program at the MIT Institute for Data, Systems, and Society (IDSS). “But there’s been a lot less research on where that organ comes from in the first place.”

In the United States, nonprofits called organ procurement organizations, or OPOs, are responsible for finding and evaluating potential donors, interacting with grieving families and hospital administrations, and recovering and delivering organs — all while following the federal laws that serve as both their mandate and guardrails. Recent studies estimate that obstacles and inefficiencies lead to thousands of organs going uncollected every year, even as the demand for transplants continues to grow.

“There’s been little transparent data on organ procurement,” argues Adam. Working with MIT computer science professors Marzyeh Ghassemi and Ashia Wilson , and in collaboration with stakeholders in organ procurement, Adam led a project to create a dataset called ORCHID: Organ Retrieval and Collection of Health Information for Donation . ORCHID contains a decade of clinical, financial, and administrative data from six OPOs.

“Our goal is for the ORCHID database to have an impact in how organ procurement is understood, internally and externally,” says Ghassemi.

Efficiency and equity 

It was looking to make an impact that drew Adam to SES and MIT. With a background in applied math and experience in strategy consulting, solving problems with technical components sits right in his wheelhouse.

“I really missed challenging technical problems from a statistics and machine learning standpoint,” he says of his time in consulting. “So I went back and got a master’s in data science, and over the course of my master’s got involved in a bunch of academic research projects in a few different fields, including biology, management science, and public policy. What I enjoyed most were some of the more social science-focused projects that had immediate impact.”

As a grad student in SES, Adam’s research focuses on using statistical tools to uncover health-care inequities, and developing machine learning approaches to address them. “Part of my dissertation research focuses on building tools that can improve equity in clinical trials and other randomized experiments,” he explains.

One recent example of Adam’s work : developing a novel method to stop clinical trials early if the treatment has an unintended harmful effect for a minority group of participants. “I’ve also been thinking about ways to increase minority representation in clinical trials through improved patient recruitment,” he adds.

Racial inequities in health care extend into organ transplantation, where a majority of wait-listed patients are not white — far in excess of their demographic groups’ proportion to the overall population. There are fewer organ donations from many of these communities, due to various obstacles in need of better understanding if they are to be overcome. 

“My work in organ transplantation began on the allocation side,” explains Adam. “In work under review, we examined the role of race in the acceptance of heart, liver, and lung transplant offers by physicians on behalf of their patients. We found that Black race of the patient was associated with significantly lower odds of organ offer acceptance — in other words, transplant doctors seemed more likely to turn down organs offered to Black patients. This trend may have multiple explanations, but it is nevertheless concerning.”

Adam’s research has also found that donor-candidate race match was associated with significantly higher odds of offer acceptance, an association that Adam says “highlights the importance of organ donation from racial minority communities, and has motivated our work on equitable organ procurement.”

Working with Ghassemi through the IDSS Initiative on Combatting Systemic Racism , Adam was introduced to OPO stakeholders looking to collaborate. “It’s this opportunity to impact not only health-care efficiency, but also health-care equity, that really got me interested in this research,” says Adam.

Making an impact

Creating a database like ORCHID means solving problems in multiple domains, from the technical to the political. Some efforts never overcome the first step: getting data in the first place. Thankfully, several OPOs were already seeking collaborations and looking to improve their performance.

“We have been lucky to have a strong partnership with the OPOs, and we hope to work together to find important insights to improve efficiency and equity,” says Ghassemi.

The value of a database like ORCHID is in its potential for generating new insights, especially through quantitative analysis with statistics and computing tools like machine learning. The potential value in ORCHID was recognized with an MIT Prize for Open Data , an MIT Libraries award highlighting the importance and impact of research data that is openly shared.

“It’s nice that the work got some recognition,” says Adam of the prize. “And it was cool to see some of the other great open data work that's happening at MIT. I think there's real impact in releasing publicly available data in an important and understudied domain.”

All the same, Adam knows that building the database is only the first step.

“I'm very interested in understanding the bottlenecks in the organ procurement process,” he explains. “As part of my thesis research, I’m exploring this by modeling OPO decision-making using causal inference and structural econometrics.”

Using insights from this research, Adam also aims to evaluate policy changes that can improve both equity and efficiency in organ procurement. “And we’re hoping to recruit more OPOs, and increase the amount of data we’re releasing,” he says. “The dream state is every OPO joins our collaboration and provides updated data every year.”

Adam is excited to see how other researchers might use the data to address inefficiencies in organ procurement. “Every organ donor saves between three and four lives,” he says. “So every research project that comes out of this dataset could make a real impact.”
