A curator (from Latin: curare, meaning "to take care") is a manager or . Traditionally, a curator or keeper of a cultural heritage institution (e.g., gallery, museum, library, or archive) is a content specialist charged with an institution's collections and involved with the interpretation of heritage material. A traditional curator's concern necessarily involves tangible objects of some sort—artwork, collectibles, historic items, or scientific collections. More recently, new kinds of curators have started to emerge: curators of digital data objects and biocurators.
In smaller organizations, a curator may have sole responsibility for acquisitions and even collections care. The curator makes decisions regarding what objects to select, oversees their potential and documentation, conducts research based on the collection and history, provides proper packaging of art for transportation, and shares that research with the public and community through exhibitions and publications. In very small, volunteer-based museums such as local historical societies, a curator may be the only paid staff member.
In larger institutions, the curator's primary function is that of a subject specialist, with the expectation that he or she will conduct original research on objects and guide the organization in its collecting. Such institutions can have multiple curators, each assigned to a specific collecting area (e.g., curator of ancient art, curator of prints and drawings, etc.) and often operating under the direction of a head curator. In such organizations, the physical care of the collection may be overseen by museum collections managers or museum conservators, and documentation and administrative matters (such as personnel, insurance, and loans) are handled by a museum registrar.
