Dissertation Abstracts (ProQuest Dissertations & Theses) contains more than 2 million entries for doctoral dissertations and master's theses. The database includes citations for materials ranging from the first U.S. dissertation, accepted in 1861, to those accepted as recently as last semester. Since 1997, new publications have been available electronically, and many publications can be ordered through the system for a fee. The database represents the work of authors from over 1,000 North American graduate schools and European universities.

Some institutions use a web-based citation manager called RefWorks. For help, check with your library staff, or see the Xavier University online help for RefWorks.
