Iowa State Dissertations
All ISU dissertations can be found in the Digital Repository @ Iowa State. A growing number of master theses can also be read and downloaded from the Repository. More information on locating ISU dissertations/theses can be found here. A few months after graduation, your thesis/dissertation will be added to the Digital Repository @ ISU. Digital Repository @ ISU will make your thesis/dissertation available to the world. In addition, a copy will be added to ProQuest's "Dissertations & Theses @ Iowa State University." You will receive an email from both of these databases notifying you as to the availability of your thesis/dissertation. In both databases, you remain the copyright holder of your thesis/dissertation.
Dissertations from other universities
There is no one database that can search all U.S., or global, dissertations. For a comprehensive look at dissertations in your subject area, you will need to search multiple databases. Please contact me directly if you cannot find a dissertation that you need.
