Non-USC Dissertations
The database ProQuest Theses & Dissertations Global is also a good source for locating digitized dissertations produced at other universities in the United States.[ProQuest Dissertations & Theses (PQDT) Global is the world's most comprehensive collection of dissertations and theses from around the world, offering millions of works from thousands of universities. Each year hundreds of thousands of works are added. Full-text coverage spans from 1743 to the present, with citation coverage dating back to 1637.]
In addition, more and more universities no longer require students to deposit their dissertations with ProQuest so you may want to search for an university's institutional repository via Google and search within that digital collection for a particular publication.
