The Cooper Union Library is a member of the Research Library Association of South Manhattan, a consortium of academic libraries established in 1977.  Consortium libraries share an online catalog and provide faculty and students of member institutions with access to each other's collections.

This agreement has made it possible for the Cooper Union Library to concentrate its collection development in the areas of Art, Architecture, and Engineering while primarily relying on the extensive holdings of the Consortium Libraries to cover the humanities and social sciences and the pure sciences.

Check with your home institution's library for further details on consortium patron privileges.
