The library catalog will be down for maintenance on Friday, Aug. 3 from 6 am to noon (continued because of an unanticipated delay). During this time search WorldCat through the library homepage OR the Beta Search tab search for CUNY books. WorldCat or the Beta Search can tell you if the Graduate Center owns a book; WorldCat and Beta Search will not provide the specific call number. For assistance finding books please contact a reference librarian at 212.817.7077, via email, or chat. The Reference Desk is located on the 2nd floor of the library.
