Finding Theses and Dissertations: Finding Lehigh Theses and Dissertations


Finding dissertations on a subject can be a somewhat confusing process because of how they are indexed. Some major abstract services include dissertations but others do not; most do not index masters theses. ProQuest Dissertations and Theses is the index to those filmed/scanned by ProQuest (previously known as UMI), which includes most US schools and some of the major international universities. Some universities have begun mounting their own disseratons and theses on the Web. Lehigh dissertations are listed in ASA, the online catalog; recent ones are linked to the PDF versions. Dissertations from other schools may be obtained either by purchase or through ILLiad. Many organizations and universities also maintain lists of dissertations in progress.
