Groups of bibliographic records are added to library catalogs with increasing frequency. Batch cataloging requires knowledge of bulk record transfer as well as current cataloging standards. While more efficient than cataloging items individually, batch cataloging requires different skills and creates new challenges. Responses to a wide-ranging online survey document the workload, tools, practices, and problems of batch cataloging. The unique characteristics of electronic resources affect many aspects of batch cataloging. Survey respondents lack consensus on how to share improved batch records, and recent trends in the bibliographic environment seem to make a networked solution less likely.
