Is there a way to narrow my search of the library catalog to just Theses without having to search through all the books?
From within the library catalog, use the Advanced search option http://opac.csuchico.edu/search/X . It is also found on the right hand navigation panel on the opening screen of the catalog.
On the Advanced search screen, use the Location pull-down menu to select Theses.
You must put a keyword in the top line of the search form, such as a topic, or your department name, or an asterisk (*) to stand in for any word. This is handy if you want to see a list of all theses.
Click search and you will retrieve theses only.
