An introduction to the uses and techniques of cataloging and classification. Focus is on a MARC (MAchine Readable Cataloging) based system. The course covers descriptive cataloging, Library of Congress and Dewey Decimal classification schemes, Library of Congress subject headings, and on-line and shared cataloging options. Emphasis is on practical rather than philosophical topics, and on practice at the level common at academic or large public libraries. Recommended to be taken early in the program.
