A Collections Management System (CMS), sometimes called a Collections Information System, is software used by the collections staff of a collecting institution or by individual private collectors and collecting hobbyists or enthusiasts. Collecting institutions are primarily museums and archives and cover a very broad range from huge, international institutions, to very small or niche-specialty institutions such as local historical museums and preservation societies. Secondarily, libraries and galleries are also collecting institutions. Collections Management Systems (CMSs) allow individuals or collecting institutions to organize, control, and manage their collections' objects by “tracking all information related to and about” those objects.[1] In larger institutions, the CMS may be used by collections staff such as registrars, collections managers, and curators to record information such as object locations, provenance, curatorial information, conservation reports, professional appraisals, and exhibition histories. All of this recorded information is then also accessed and used by other institutional departments such as “education, membership, accounting, and administration."[2]
