The Library of Congress was the topic of the October, 1975, meeting of the Association of Research Libraries (ARL). Presentations were given on: (1) the future uses of automation to aid the Library of Congress in its authoritative information and bibliographic data collection and dissemination functions; (2) the progress and projections for the MARC (machine readable cataloging) distribution service and retriever; (3) the national and international automated networks of the Library of Congress; and (4) the process of transition to the Library's automated systems. The director of the research grant division of the National Endowment for the Humanities introduced the library-related programs of her division. The National Commission for Libraries and Information Science made a progress report on the development of a national information service program. Reports of ARL commissions and executives followed in the business meeting. (KB)
