This document discusses cooperative cataloging, which involves multiple libraries sharing the work and costs of cataloging books for their mutual benefit. It defines cooperative cataloging as when independent libraries cooperate to produce a catalog for their benefit. The objectives are better resource use, standardization, economy, improved services, and union catalogs. Advantages include cost savings through shared labor and resources, eliminating duplication, ensuring quality cataloging, uniformity, and increased quantity of cataloged books. Disadvantages can include loss of cataloging jobs and inability to participate if libraries use different formats.
