PQDT Open (Open Access dissertations)

  • PQDT Open is a list of Open Access dissertations provided by ProQuest.
  • It is not searchable from within ProQuest.
  • The easiest way to search it is to go the link above and do a text find (Ctrl+f Windows; Command + f Mac) from within your browser.
  • You can search for key terms or author names.
  • The PQDT Open dissertations are also searchable by search engine.
  • For best results do a title search with the title in quotation marks, and with the author's name outside the quotation marks. E.g. "Scandium oxide thin films and their optical properties in the extreme ultraviolet" Acosta

Commercially Published Theses or Dissertations

  • Dissertations are sometimes published commercially (and often with a different title). Check the TWU Catalogue or WorldCat, and search by author name.

Discipline-related Databases

  • Some theses and dissertations may not be available through any of the means above, but the authors may have published journal articles based on their research. Searching a specialized database (Article Databases) for the author's name and adding keywords related to the topic of his/her research, may find articles they have published. In addition, some databases, CINAHL, MLA Bibliography, PsycInfo, etc. index theses and dissertations.
