Five Colleges Library Catalog
To find books at UMass only, use the Five Colleges Library Catalog and select the UMass link (top right).
To cast a wider net, search all Five Colleges at once. You can get any physical book from the other colleges delivered here.
For the widest search, use WorldCat. This finds titles whether the UMass Amherst Libraries have access or not.
If a book you want is not available in the Five College Library System, request a copy to borrow for free through InterLibrary Loan.
