We are pleased to announce that MassCat is now part of the Commonwealth Catalog (ComCat). MassCat is a small network, partly underwritten by the Massachusetts Library System, to support small and unique libraries which don’t quite fit into the nine large networks in Massachusetts. MassCat offers it’s libraries a completely web-based platform for circulation, cataloging, ILL, acquisitions and serials management. Currently, most MassCat public libraries are online. MassCat school libraries will come onto ComCat in October. The Massachusetts Library System’s Professional Collection circulates on MassCat, providing all of our members with direct access to the collection of over 500 librarian curated titles on library topics.
