To find Columbia theses and dissertations that are not available in full-text online (above), search CLIO: Dissertations (this searches both the Library Catalog and Academic Commons). The catalog treats theses and dissertations like books. Search by author, title, keyword or LC subject heading. In the catalog, the term "thesis" denotes both Masters' theses and dissertations. A keyword search for "thesis" and "Columbia University" will find all theses and dissertations produced at Columbia. You may also narrow your search by including the name of the department or school.
