DRS Reaches 500,000 Uploads

The Digital Repository Service (DRS) is now home to more than half a million files! We don’t know exactly which newly uploaded file was the 500,000th to be added to the system, but it was likely a digitized image from the Mills College Art Museum — possibly one of the etchings by Stefano della Bella, Jan Georg van Vliet, or Theodorus van Kessel.

This etching on paper by Italian draughtsman and printmaker Stefano della Bella is likely to have been one of the works that brought the DRS to its 500,000th upload.

This milestone comes as the library celebrates a decade of supporting the DRS as a service for the university community. In those 10 years, a few files have emerged as the most popular, seeing consistent traffic year after year, including:

Capturing Scholarship: Electronic Theses and Dissertations in the DRS

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:

  1. Export the files and move backups to other networked drives
  2. Record submissions in a spreadsheet to ensure file provenance
  3. Document any additional information, such as embargo dates or original file names, in case there are issues with the submission
  4. Review, normalize, and transform the existing ProQuest metadata to create DRS-compliant records for each file
  5. Add degree, school, and department information to each record to support the DRS collection structure
  6. Ingest the ETDs into their corresponding collections in the DRS
  7. Generate digital object identifiers (DOIs) for each ETD
  8. Conduct name authority control on all advisor and committee member names

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%.

College, School, Department, and Program Representation

The early majority of ETDs produced by Northeastern students were from the College of Engineering (COE), which accounted for almost 62% from 2008-2010. Throughout the 2010s, other colleges emerged as significant contributors, including the Bouvé College of Health Sciences, the College of Professional Studies (CPS), and the College of Science (COS).

Within the College of Engineering, Electrical and Computer Engineering and Mechanical and Industrial Engineering remain the most prolific ETD producers, as well as the Chemistry and Chemical Biology program, the School of Education, and the Department of Art + Design.

The top 10 departments by total submission count:

  1. School of Education (2,143 submissions)
  2. Department of Electrical and Computer Engineering (910)
  3. Department of Mechanical and Industrial Engineering (705)
  4. Department of Chemistry and Chemical Biology (316)
  5. Department of Art + Design (271)
  6. Computer Science Program (245)
  7. Department of Civil and Environmental Engineering (242)
  8. School of Pharmacy (212)
  9. Department of Chemical Engineering (209)
  10. Department of Counseling and Applied Educational Psychology (202)

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.

10 Years of the DRS: Environmental Voices

In our series of posts highlighting 10 years of the Digital Repository Service (DRS), I wanted to shine a light on the audio and video materials we host that engage with global warming, pollution, and the climate emergency.

Student Research

The annual Research, Innovation, and Scholarship Expo (RISE) is an opportunity for students and faculty to showcase their research focused on solutions to real-life problems. In 2021, these presentations were recorded.

  • The debt calculator: a gratitude-based approach to environmental justice by Kira Mok and Sophie Kelly describes how Chelsea and East Boston have a higher burden of pollution and negative health consequences compared to more wealthy parts of Boston, which benefit from industry in these neighborhoods. Their project “What Does Chelsea Do for You?” led to an infographic and online quiz about the debt Boston residents owe to these areas.
  • Northeastern University green chemistry education symposium, a presentation by Olivia Sterns, Umin Jalloh, Christopher Mahir, Christina McConney, and Angelica Fiuza, describes a sustainable and environmentally responsible chemistry curriculum and plans for a related conference. You can also check out the organization Beyond Benign.
  • The impact of biological knowledge on pro-environmental behavior is a presentation by Kyleigh Watson, Kelly Marchese, Jasmine Ho, and Daniela Ras that explores the relationship between study participants’ knowledge of nature, urbanicity, and implicit and explicit connection to the natural world.

Podcast Episodes

The What’s New podcast, hosted by Dean of the Library Dan Cohen, is one of the most popular collections in the DRS. It consists of wide-ranging conversations with faculty members across the university.

Coursework

The DRS team also works with professors to host student coursework in the repository.

If you’ve seen pictures of campus happenings, then you’ve seen the hard work of the Northeastern University photographers. This team is responsible for documenting the day-to-day activity that takes place on Northeastern’s campuses, capturing everything from sporting events to researcher portraits to candid photos of students going about their day.

Matthew Modoono, Alyssa Stone, and many other photographers in the Communications Office have used their cameras to document life at Northeastern for decades. They have been recognized by the University Photographers Association of America, the National Press Photographers Association, and the New England Newspaper & Press Association, and have received several awards, including Picture of the Year and Photographer of the Year, for their tremendous skill and vision in the field of photography.

Library staff are responsible for archiving the printed photographs captured through 2010 (digitized copies are also available in the Northeastern University photograph collection (A103). Since 2010, we also help facilitate access to their digital collection in the Digital Repository Service’s Communications Photo Archive (access to the photographs in this collection are limited to Northeastern faculty and staff).

The Communications Photo Archive has served as a record of recent activity since 2015, when the Digital Repository Service first launched. Since then, the photographs stored in the collection (more than 172,000 at the time of this writing) have been viewed and downloaded approximately 400,000 times. The photographs can be seen in many places around the university, including websites, printed brochures, magazines, social media, and in the daily articles published in Northeastern Global News.

Photographs of commencement make up a large portion of the collections, with about 20% of the 172,000 photos described using the terms “graduation” or “commencement.” In fact, some of the busiest days for uploading photographs to the DRS happen during the commencement season, with photographers regularly adding more than 1,000 photographs a day.

Although the photographs in this collection are only available to Northeastern faculty and staff, the collection regularly appears in the list of the top 10 most-used collections in the DRS — a testament to how important the photos are to the day-to-day work at the university.

Be sure to check the Communications Photo Archives regularly for the most recent photos of life at the university. You can sort search results by “Recently created” or “Recently updated” to view the most current shots. You may also click the “Recently added” button to sort the entire collection by the most recently uploaded images. The “Limit your search” button can be used to limit your results by the name of the photographer or the year the photograph was taken.

Contact me or my team for help using the DRS or finding photographs in the collection. Visit the Brand Center’s Photography page for information about the photographs and photographers, as well as how you can access the photographs and use them for university business.

And please enjoy some of my favorite photographs from the Communications Photo Archive: animals on the Boston campus!

100,000 public items available in the DRS!

The 100,000th publicly available file in the Digital Repository Service was deposited in July: a dissertation from the English Department titled Women Writing Racelessness: Performativity And Racial Absence In Twentieth Century Women’s Writing, by Sarah Payne. This milestone was achieved through the library’s and the university’s commitment to supporting open access to the scholarly output of the university, as well as to the archival artifacts that document the university’s history.

Many of the 100,000 public files are discoverable through Google and other search engines, as well as portals like the Digital Commonwealth and the Digital Public Library of America, which are designed to bring together digitized materials from various sources. Thanks to the openness of these materials, the DRS averages more than 2,000 unique visitors and more than 3,600 file interactions each day. Public materials stored in the DRS have been cited by regional and national news organizations, including the New York Times and WBUR, as well as in Reddit discussions and Wikipedia articles.

Here are a few digital collections for you to explore:

The DRS will continue to grow as Northeastern faculty, staff, and students continue to produce articles, images, research, and artifacts that represent the tremendous work happening at the university. Faculty and staff are welcome to sign in to the DRS and upload their own research publications, presentations, monographs, and datasets at their leisure. To get started uploading lots of materials for large projects, contact your subject librarian or the library’s Repository Team: Library-Repository-Team[@]neu.edu.
