This document provides an overview of cataloging concepts and standards. It discusses what cataloging is, the different types of cataloging (original vs. copy cataloging), and the key elements included in catalog records like bibliographic description, subject analysis, and classification. The document also explains historical standards like ISBD and AACR2 and emerging models like FRBR, FRAD, and RDA which aim to improve resource discovery in the digital age. While original catalogers need detailed rules knowledge, most school librarians can get by with a general understanding of standards and knowing where to find detailed rules when needed.
