Abstract

The use of computerized cataloguing data requires a commitment on the part of libraries to the standardization of data elements and record formats. Early computerized formats were initiated by several research libraries to serve the needs of particular university systems. In developing MARC, the LoC drew on the experiences of these libraries in establishing a standard acceptable to the research library community for the interchange of bibliographic data. Discusses early computerized formats influencing MARC, the origins of the MARC Pilot Project, and design factors influencing the evolution of the format through MARC2. Research was based on primary sources documenting the early history of MARC, including unpublished documents in the LoC archives
