MRMC II, developed and used by the LC Manuscripts Division, is an expanded version of the MRMC system designed for administrative control. After modifying the system several times since its creation in 1967, the staff decided in 1973 that major changes were desirable. Enhancements made possible the production of catalog cards and a cumulative index to the Division's holdings, thus providing access as well as administrative control. These modifications were based on the LC MARC II format (record structure, content, and coding) and were intended to be compatible with the MARC format for manuscripts.
