REGISTER  , a

record of facts, proceedings, acts, events, names, &c., entered regularly for reference in a volume kept for that purpose, also the volume in which the entries are made . The Fr. registre is taken from the Med . Lat. registrum for registum, Late Lat. regesta, things recorded, hence list, catalogue, from regerere, to carry or bear back, to transcribe, enter on a roll . For the keeping of public registers dealing with various subjects see REGISTRATION and the articles there referred to, and for the records of baptisms, marriages and burials made by a parish clergyman, see section Parish Registers below . The keeper of a register was, until the beginning of the 19th century, usually known as a " register," but that title has in Great Britain now been superseded by " registrar "; it still survives in the Lord Clerk Register, an officer of state in Scotland, nominally the official keeper of the national records, whose duties are per-formed by the Deputy Clerk Register . In the United States the title is still " register." The term " register " has also been applied to mechanical contrivances for the automatic registration or recording of figures, &c . (see CASH REGISTER), to a stop in an organ, to the compass of a voice or musical instrument, and also to an apparatus for regulating the in- and outflow of air, heat, steam, smoke or the like . Some of these instances of the application of the term are apparently due to a confusion in etymology, with Lat. regere, to rule, regulate .
