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:

In September, Northeastern University Archives and Special Collections (NUASC) hosted the staff of The Huntington News for an open house to view campus collections dating back from 1926-2009. This event was held in part to help The Huntington News staff prepare to celebrate their centennial year in February 2026 and to introduce the past news issues at their disposal for future research.

The Huntington News has recently been leveraging the archives in their reporting, with archival records featured in many stories. Their From the Archives series chronicles important events and eras in the university’s past with support from primary source materials such as documents and photographs.

NUASC is fortunate to steward multiple student news publications, including Northeastern News (and its predecessor, The Northeastern Tech); Panga Nyeusi, Northeastern’s first Black student newspaper; and the Black student-run Onyx Informer. Many of these materials can be accessed online through the Digital Repository Service.

While flipping through old issues of Northeastern News, Huntington News staff members were able to see the marked differences between the various eras of the News. While older issues featured more text, shifts in reporting and design led to more photographs in later editions. They were also able to compare reporting from the present to similar themes in the past, such as on-campus demonstrations and rapidly developing new technologies.

Staff members were welcome to use the microfilm reader that is housed in the reading room to view News issues. While there is a material difference between scrolling through microfilm and leafing through a newspaper, there are benefits to both methods of researching past issues. Microfilm provides quick access to specific issues and a compact way of storing information from print resources. Physical news issues give researchers the opportunity to engage with an item in the same way that someone would have when the issue was first printed.

Student news has been a vital part of the Northeastern campus community since its inception in the early 20th century. These publications are available in physical form and can be viewed in the NUASC reading room. If you would like to view these or any materials in the archives, please make an appointment by contacting archives@northeastern.edu.

A fundraising opportunity to digitize the news is coming soon and will be announced in the new year. NUASC is excited to collaborate with The Huntington News to expand access to these historic records.

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.
