    Abstract
    The MARC Program of the Library of Congress, led during its formative years by the author of this entry, was a landmark in the history of automation. Technical procedures, standards, and formatting for the catalog record were experimented with and developed in modern form in this project. The project began when computers were mainframe, slow, and limited in storage. So little was known then about many aspects of automation of library information resources that the MARC project can be seen as a pioneering effort with immeasurable impact.
