Commonwealth Catalog

If you can't find it in the CW MARS catalog, you can search other libraries across the Commonwealth of Massachusetts via the Commonwealth Catalog.  

Requests will be delivered to your local library for pickup. 

Requesting in ComCat is open!

Please allow a little extra time when requesting for materials to be handled, processed, and quarantined. And as always, don't forget to search the CW MARS catalog before trying ComCat.

If you have any questions about ComCat services, check out their FAQ. Additional questions can be addressed to your local library.

Log in to place, manage, and cancel requests in the statewide Commonwealth Catalog.

Need Help? Visit the Commonwealth Catalog FAQ or contact your local library for assistance.

Funding for the Commonwealth Catalog is provided by the Massachusetts Board of Library Commissioners and the Institute of Museum and Library Services.
