Dissertations can be borrowed on the book form. All you need to provide on the form is the title, author, and year of the dissertation.
Note: Before you request a dissertation through ILL, you should first check to see if the full-text is available in Dissertations & Theses: Full-Text, a database that contains the full-text for most dissertations published in the United States since 1997. You can find this database listed in the Articles and Database page of the Library website.
