Theses (Masters) and dissertations (PhD) are essential sources of information for emergent areas of research and scholarly communication. Different search engines and databases provide both unique and overlapping coverage of these types of documents. ProQuest Dissertations and Theses Global provides coverage from mainly North American, increasingly world-wide and English-speaking institutions since 1861. A reminder that not all theses and dissertations are released or available in full-text format. Contact the Library if you have any questions or problems.
