A union catalog of libraries from around the world (mostly in the U. S.), Worldcat Includes books, media, manuscripts, and other formats dating back to the 12th century. It also has a mobile website. You must have a John Jay College email address to search Worldcat. Other CUNY affiliates can use this alternate address and enter their CUNY library ID barcode when prompted.
If needed, graduate students and faculty can order materials via Interlibrary Loan.
Use the Library of Congress Online Catalog to search the approximate 12 million records representing books, serials, computer files, manuscripts, cartographic materials, music, sound recordings, and visual materials.
