About CollectiveAccess

CollectiveAccess is open-source collections management and presentation software designed for museums, archives, and special collections. As it is highly flexible and easily customized, it is also increasingly used by libraries, non-profits, private collectors, artist studios, performing arts organizations and other groups around the world. At its core, CollectiveAccess is a relational database that enables complex cataloging, powerful searching and browsing and nuanced web-based collection discovery.

CollectiveAccess is a collaboration between Whirl-i-Gig, a New York-based development team, and partner institutions in North America and Europe with projects in 5 continents.
