content: The Library of Congress has been developing MARC (Machine Readable Cataloging) records since the 1960s. Users of the computerized system received materials from The Library Corporation (now TLC) of Inwood, Virginia, since that firm was founded in 1974. By 1984, microfiche with new records were sent to participating libraries and bookstores weekly. In 1985, the Library Corporations switched to distributing MARC records on CD-ROM. NMAH acquisition 1991.0185 consists of an example of a laser disc drive made by Hitachi used for this distribution, as well as three compact discs with records. Acquisition 1991.3031 consists of a later Hitachi disc drive with discs distributed in 1988, 1990, and 1991.
