Cataloging Process

• A book ordered by the Acquisition Department is given to the Cataloging Department. The Catalog Department identifies the book. Next, the cataloger create a MARC record for the book by one of three ways, either creating the information, using the publisher information or accessing the Library of Congress catalog information. The complete MARC record information is used to update the library’s databases for authority control, books and authors. The cataloger then creates a public catalog card from the MARC record. The card is added to the OPAC. The barcode and spine labels for the book are prepared, printed, and attached to the book. The book is then sent to the Circulation Department.
