A curator (from Latin: curare, meaning "to take care") is a manager or overseer. 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.
