About Us

Central/Western Massachusetts Automated Resource Sharing, Inc., is a library consortium dedicated to efficient resource sharing and rapid access to information.

Our 155 member libraries circulate more than nine million items annually to one million registered borrowers. We offer a shared online computer system and combined collections of more than six million items.

Due to the size and diversity of C/W MARS, services may vary at member libraries. C/W MARS receives partial funding from the Massachusetts Board of Library Commissioners. Additional support comes from members' fees.

Please contact the staff at your local C/W MARS member library if you have additional questions about C/W MARS or the services available to you via your library's membership in C/W MARS.

Thank you.
