Dissertations and Theses

Dissertations and Theses

In Library resources, the words "theses" or "thesis" used alone includes both doctoral dissertations and master's theses.

The primary database for searching and identifying theses and dissertations is ProQuest Dissertations & Theses, often called Dissertations Abstracts.
