Many databases cite doctoral dissertations but as a general rule, the Library does not acquire doctoral dissertations. In rare cases when the Library purchases a dissertation, it is treated as a " library book" and it is cataloged and shelved as such. To find out if the Library owns a particular dissertation, in OneSearch, search for author and title.
For CUNY dissertations available via the Graduate Center, see: https://libguides.gc.cuny.edu/c.php?g=1001003&p=7247665 .
WorldCat lists dissertations available at other libraries, and these might be available for loan. Check WorldCat holdings prior to requesting specific dissertation via Interlibrary Loan.
Dissertations not available otherwise can be purchased via the ProQuest Dissertation Express .
