Dissertation Reviews is a new site that features overviews of recently defended, unpublished doctoral dissertations in a wide variety of disciplines across the Humanities and Social Sciences. Their goal is to offer readers a glimpse of each discipline’s immediate present by focusing on the window of time between dissertation defense and first book publication. Each review provides a summary of the author’s main arguments, the historiographic genealogy in which the author operates, and the main source bases for his or her research. The reviews are also anticipatory, making educated assessments of how the research will advance or challenge our understanding of major issues in the field when it is revised and published in the future.

Holds 800,000 dissertations from universities outside the U.S. and Canada. However, only 20,000 of these are cataloged in the database. If you know the exact title of a dissertation and do not find it in the database, CRL recommends searching the CRL Catalog. If the title does not appear in the database or the catalog, contact CRL directly to inquire if it is held. CRL continues to acquire about 5,000 titles per year from major universities.
