Try ProQuest's Dissertation Express. If you find one that you need, you can return to the sites mentioned above to see if it's available freely online or in a library near you. If not, you have the option to purchase it from ProQuest.
See if the author wrote an article, book chapter (or entire book)based on his/her thesis or dissertation. Also search for publications written by the author's dissertation chair, if you can find that name (often listed on the title page). Click here to learn how to search by author.
Note about interlibrary loan for theses and dissertations: While our library does offer an interlibrary loan (ILL) service, many libraries do not lend theses and dissertations outside of their own institutions, simply because so few print copies of each one are made. It may be possible to have a limited number of pages scanned and emailed or copied and mailed via ILL. But, we encourage you to try the suggestions above before resorting to ILL.
