The world’s largest collection of doctoral theses, in one account
The ProQuest Dissertations Theses access is the reference database for graduate research — the single biggest gathering of doctoral theses and dissertations in the world, spanning universities on every continent and every academic field. Most recent work is available in full text, so you read the whole study, not a summary.
Inside this resource
Millions of theses, worldwide
The collection runs to millions of dissertations submitted at universities around the globe, which makes it the natural first stop when you need to know what has already been researched on a topic.
Full text with ProQuest Dissertations Theses access
The majority of recent submissions are available as complete documents, so you can read methodology, results and full reference lists — invaluable when scoping a literature review or checking prior art.
Every discipline in one place
From medicine and the sciences to the humanities and engineering, coverage spans all academic fields, so interdisciplinary searching stays inside a single database.
Who this serves
- PhD and master’s candidates — find precedent studies, methodologies and gaps before committing to a research question.
- Supervisors and examiners — check what has been done in a field and how comparable theses were structured.
- Systematic reviewers — capture grey literature and unpublished doctoral work that journal databases miss.

L. Fischer –
Huge database. A few older theses were citation-only but most recent ones opened in full, which is what I needed.
Dr. Ken A. –
Found three dissertations on my exact topic within an hour. Full text on the recent ones saved me weeks of scoping.
Dr. Yara H. –
Coverage is excellent. I’d have liked cleaner export of references, but the source material itself is exactly what I came for.

Best place to see what methodology other people used before you lock in your own. Global coverage is real.

Great for capturing grey literature in a systematic review. Webproxy login was straightforward.
