Enriching research. Expanding possibilities. Since 1949.

The Center for Research Libraries (CRL) is an international consortium of university, college, and independent research libraries. Founded in 1949, CRL supports original research and inspired teaching in the humanities, sciences, and social sciences by preserving and making available to scholars a wealth of rare and uncommon primary source materials from all world regions.

CRL's deep and diverse collections are built by specialists and experts at the major U.S. and Canadian research universities, who work together to identify and preserve unique and uncommon documentation and evidence, and to ensure its long-term integrity and accessibility to researchers in the CRL community.

CRL is based in Chicago, Illinois, and is governed by a Board of Directors drawn from the library, research and higher education communities.
