The Keeper of the Register (more formally known as the Keeper of the National Register of Historic Places) is a National Park Service (NPS) official, responsible for deciding on the eligibility of historic properties for inclusion on the U.S. National Register of Historic Places (NRHP). The Keeper's authority may be delegated as he or she sees fit. The State Historic Preservation Office for each state submits nominations to the Keeper. Upon receipt, the Keeper has 45 days to decide whether to add the property to the NRHP.
