The BIBCO Standard Record (BSR) is a model for bibliographic monographic records using a single encoding level in a shared database environment. Catalogers satisfy BSR requirements when creating and/or modifying bibliographic records, and determine the level of fullness that best suits the resources in their collections and the needs of their users.

The BSR is a "floor record" which emphasizes access points over extensive, redundant descriptive data. It provides catalogers with a set of mandatory elements and mandatory if applicable elements appropriate to various bibliographic formats. These elements have been determined to support user needs to find, identify, select, and obtain resources. Authority records must support controlled access points in a BSR.

Elements in the BSR Metadata Application Profiles (MAPs) are accompanied by use values and, in some cases, prescription for subfields or other basic points. It is recognized that institutions may not want or need to use the BSR for every material type. BSRs for all material types share these Characteristics (PDF, 22 KB).

Official RDA [beta version for training purposes only]

The BSR MAP for Official RDA is a beta version intended for training purposes only.

PCC will be implementing Official RDA in 2027. This application profile for the BSR is intended for use in training by the PCC community and should not be used currently for cataloging in production by BIBCO catalogers. It is expected that the use of the application profile in training and testing over the next year will result in a number of refinements to the application profile.

Original RDA [current]

The BSR MAP for Original RDA includes elements applicable to archival materials, audio recordings, cartographic resources, electronic resources (if cataloged in the computer file format), graphic materials, moving images, notated music, rare materials, and textual monographs. The MAP is arranged in RDA element order.

AACR2 [superseded]

The BSR MAPs for AACR2 below are obsolete and should not be used in current BIBCO cataloging. They are archived here for historical interest only. Elements in the MAPs are arranged in MARC field order.
