No. ProQuest Research Library (available to members of the USC Alumni Association) does not contain dissertations. Alumni and non-USC affiliated patrons have two online options to access dissertations:

• USC dissertations (and many theses) created since Fall 2006 are available in the USC Digital Library.  
• For dissertations from other institutions, search Open Access Theses and Dissertations.

For more information about dissertations, consult the Dissertations Research Guide.
