C/W MARS, Inc.

C/W MARS provides technology for member libraries to share resources and enhance access for their communities.

C/W MARS is a diverse multi-type library consortium made up of over 165 member libraries located in Central and Western Massachusetts. C/W MARS is an acronym that stands for Central/Western Massachusetts Automated Resource Sharing.

Our membership is made up of academic, public, and special Massachusetts libraries of all sizes, from tiny towns with populations under 500 to large urban libraries with many branches. C/W MARS hosts and supports the hardware and software needed to power our shared online library catalog and library staff software. We provide technical support to member libraries and managed Internet services.
