Did you know we have access to…Scopus AI?
Scopus AI creates a Wikipedia-like summary in response to a research question, backed by peer-reviewed sources from Scopus. An interactive concept map, surfacing of research themes, and leading authors all help to give researchers further insight into a topic, as well as suggestions for further exploration.
Northeastern’s electronic theses and dissertations (ETDs) provide a valuable record of the university’s scholarly contributions, capturing the evolution of research across numerous academic disciplines over the past two decades. The Digital Repository Service (DRS) preserves all ETDs from 2008 onward, along with selected earlier works, creating a collection of more than 7,500 items spanning over 30 departments and nearly 70 academic programs.
As some of the DRS’ most frequently accessed materials, ETDs offer rich insights into the university’s academic history and digital presence. To celebrate the 10th anniversary of the DRS, Digital Production Services (DPS) — the department responsible for managing both the DRS and ETDs — set out to share insights into how theses and dissertations are added to the repository and how Northeastern’s ETD collections have evolved over time.
ETD Creation to DRS Ingest: Process Overview
The ETDs are initially submitted to ProQuest by graduate students as a condition of their graduation. The rules for the submission package and document organization are determined by each program. Once the submission is completed and the student fills out information about their ETD, the file and metadata are sent in via a zip file to a library server. Over the last 5+ years, a local workflow has been developed to:
Export the files and move backups to other networked drives
Record submissions in a spreadsheet to ensure file provenance
Document any additional information, such as embargo dates or original file names, in case there are issues with the submission
Review, normalize, and transform the existing ProQuest metadata to create DRS-compliant records for each file
Add degree, school, and department information to each record to support the DRS collection structure
Ingest the ETDs into their corresponding collections in the DRS
Generate digital object identifiers (DOIs) for each ETD
Conduct name authority control on all advisor and committee member names
Filtering options for ETDs in the DRS.
New ETDs are processed and ingested every 2-3 months, depending on the time of year and the volume of ETD submissions, and can involve anywhere from 30 to 100 ETDs at a time. DOIs are generated and ETD contributor names are reviewed bi-annually.
General Growth
The total number of ETDs submitted by Northeastern students has increased significantly since 2008. From 2008-2010, there was an average of around 190 documents submitted annually. As the 2010s continued, that number steadily increased from 353 in 2013 to 583 in 2019. There was a small dip in 2020, possibly due to COVID interrupting degree completions, but since then, there have been approximately 540-590 ETDs submitted each year.
Degree Distribution
Almost 90% of ETDs produced from 2008-2010 were either for Ph.D. or MS degrees, but as the School of Education started producing theses for the Ed.D. degree, those quickly became common, and represented 34% of all ETDs produced by 2020. Additional degree programs also started producing ETDs from 2010-2020, with MA, DLP, and MFA degrees representing almost 5% of ETDs during that period. In the last 4-5 years, numbers have stabilized, with Ph.D. dissertations regularly accounting for around 45% of all ETDs, Ed.D. theses around 35%, MS theses hovering around 15%, and all other degree types filling out the remaining 5%.

Addition of Supplementary Files
The first ETD to include supplemental files, or files submitted to accompany the ETD PDF file, first appeared in 2013. The number of supplemental files grew throughout the 2010s, with supplemental material representing 4% of all ETD file submissions during that time. Since 2020, the number of supplemental files has seen a slight decline, but there are still regular submissions, with 26 provided in 2024. The college that most often submits these files is the College of Arts, Media, and Design (CAMD), with almost 1 in 4 theses including supplemental materials.
Other notable contributors include COE and the College of Social Sciences and Humanities (CSSH). The smallest contributor is CPS, which, despite being the largest contributor of ETDs overall, has only 11 total supplemental files since 2013.

New Undergraduate Theses
More recently, undergraduate programs from departments like Biology, Biochemistry, Marine and Environmental Science, and Psychology have begun to submit electronic theses directly to DPS staff. DPS offers the same level of service to the undergraduate theses as the graduate ETDs and includes the same metadata in each accompanying description to ensure these materials are as discoverable as the graduate theses and dissertations.
Maintaining ETDs is a vital part of the DRS’ mission, presenting unique challenges that library staff are well-equipped to manage. As the submission processes, file formats, academic disciplines, and research topics continue to evolve, the library remains committed to preserving and providing access to these scholarly works. Through ongoing innovation and stewardship, we ensure that the academic contributions and history of Northeastern students are securely archived and shared for generations to come.

The Digital Repository Service (DRS) is an institutional repository that was designed by the Northeastern University Library to help members of the Northeastern community organize, store, and share the digital materials that are important to their role or responsibilities at the university. This can include scholarly works created by faculty and students; supporting materials used in research; photographs and documents that represent the history of the community; or materials that support the day-to-day operations of the university.
While the DRS itself is a technical system that stores digital files and associated information to help users find what they need, we also consider the DRS to be a service for the university community: library staff are here to help you organize, store, share, and manage the digital materials that have long-lasting value for the university community and beyond.
Published research from the Northeastern community available in the DRS.
Northeastern is not alone in this endeavor. Repository services are now standard practice for most academic institutions, including Harvard University Library (who also use the name “Digital Repository Service”), Stanford University Library (a leader in technical development for repository systems), Tufts Libraries, and other institutions around the world.
Who uses the DRS?
The DRS has been used by faculty, staff, students, and researchers from all corners of the university community for 10 years. There are too many use cases to mention in one brief blog post, but here are some trends we’ve seen in what users choose to deposit the last few years.
Publications and data that supports published research
Event recordings, photographs, newspapers, and almost any kind of material you can think of to support the day-to-day operations and activity at the university
Student research projects and classwork, like oral histories and research projects. Students are also required to contribute their final version of their thesis or dissertation.
Digitized and born-digital records from the Archives and Special Collections, including photographs, documents, and audio and video recordings
These files, and all the other audio, video, document, and photograph files in the DRS, have been viewed or downloaded 11.2 million times since the DRS first launched in 2015. Nearly half of the files in the DRS are made available to the public and are therefore available for the wider world to discover. Materials in the DRS have been cited in reporting by CNN, Pitchfork, WBUR, and Atlas Obscura, among others, and are regularly shared on social media or in Reddit threads. As a result, Northeastern continues to contribute the work produced here to the larger scholarly and cultural record, and to the larger world.
Who supports the DRS?
The day-to-day work managing, maintaining, and supporting users of the service comes from staff in Digital Production Services:
Kim Kennedy supervises the digitization of physical materials and processing of born-digital and digitized materials.
Drew Facklam and Emily Allen create and maintain the descriptive metadata that helps you find what you need.
And all of us in the department, including part-time staff, are responsible for general management of the system, including batch ingesting materials, holding consultations and training sessions, answering questions, and leading conversations about how to improve the system and the service.

The DRS is also supported by a number of library staff members across the library:
David Cliff, Senior Digital Library Developer in Digital Infrastructures, is the DRS’ lead developer and system administrator.
Ernesto Valencia and Rob Chavez from the Library Technology Services and Infrastructure departments also provide development support and system administration.
Many librarians in the Research and Instruction department do outreach about the service and support faculty as they figure out how to use it in their work.
Jen Ferguson from Research Data Services also connects faculty and researchers to the DRS, while also providing data management support for those wishing to use the DRS to store their data.
Members of the library administration, including Dan Cohen, Evan Simpson, Tracey Harik, and the recently retired Patrick Yott have contributed their unwavering support and advocacy for developing and maintaining system an service.
We are all here to help you figure out how the DRS may be used to make your work and academic life easier. To dive deeper into what the DRS is and how to use it, visit the DRS subject guide or contact me or my team.
As Northeastern University’s community continues to expand, the library strives to provide equitable access to our resources, maintaining an e-preferred collections policy. For items outside of our collections, interlibrary loan is integral—and this service includes borrowing e-books whenever possible.
In 2023, representatives from 11 member institutions within the Boston Library Consortium (BLC) formed the eBook Sharing Working Group. I was proud to co-chair the group with Marc Hoffeditz, Resource Sharing Manager of the BLC. Pamela Diaz, Northeastern’s Resource Sharing Lending Coordinator, was also a member. Our charges were:
Investigating a vendor-neutral, consortial approach to e-book borrowing and lending.
Crafting documentation to detail e-book borrowing and lending procedures, including license negotiations, holding considerations, system alterations, and adaptable workflows.
Exploring potential avenues for consortial e-book sharing, advocacy, and group acquisitions.
