Training new collection managers (bibliographers) in an academic research library is an enduring challenge, especially in the modern collections environment. Many bibliographers come to the job with limited subject expertise, and must also master a constantly evolving collection development environment featuring interdisciplinary collecting, aggressive cooperative purchasing, and a myriad of technological issues. This paper examines collection manager training at UC Santa Barbara. It describes a new program of training sessions, and the concurrent creation of a "Collection Managers' Manual" (http://www.library.ucsb.edu/collman) of advice and information for the subject bibliographer.
