The Iowa State University Digital Repository provides open access to the full-text of many theses and dissertations completed at Iowa State University. From this page, you can either browse our theses and dissertations by academic department or by the year of completion.

Some Iowa State theses and dissertations are not eligible for open access. These may be accessible, with some restrictions, via ProQuest/UMI. On the ProQuest site, the full text of Iowa State's digital theses and dissertations can be viewed by members of the Iowa State community (current students, faculty, and staff) or individuals searching from Iowa State campus IP addresses. Others can view only the first 25 pages of a thesis or dissertation from Iowa State

Finally, some Iowa State theses and dissertations exist only in paper format. For more information, see How to find dissertations and theses through the Iowa State University Library, or contact your subject librarian.
