Advanced Searching Tip: You can use subject and name headings to search within topics, as identified by library catalogers, or for specific people (authors, dancers, choreographers, composers, etc.). One way to do this is to search the Library of Congress Authority File (linked below) for authorized forms of subject headings and name headings.  Once you have identified these headings, you can use them in a search for bibliographic records in Library Search, MelCat, or WorldCat.  Another way to do this is through triangulation by performing a keyword search, finding records for library items you will use, and finding the subject headings and name headings in those records.

Many dissertations are available online. If not online, they can usually be borrowed through interlibrary loan.
