Finding dissertations and theses in the field of Middle East Studies:
You will probably most often find what you need through the ProQuest Dissertation & Theses database which contains dissertations and theses from U.S. and Canadian institutions
American Doctoral Dissertations, 1933-1955 provides electronic access to the only comprehensive record of dissertations accepted by American universities during that time period, the print index Doctoral Dissertations Accepted by American Universities. Containing twenty-two years of dissertation research and amounting to nearly 100,000 citations, it was created with the generous support of the H. W. Wilson Foundation and the Congregational Library & Archives in Boston.
Note: While the records for each dissertation show a link to a full text PDF, these are PDFs of the original print index, NOT the dissertations themselves.
