Description/Instructions

The bibliographic level is a one-character alphabetic code that indicates the bibliographic level of the record. The only code currently used for serials is code "s" which is automatically generated in the OCLC serial work form. Code "i" has been defined for integrating resources, however code "m" is currently being used. See B7 for an explanation of the coding practice for integrating resources until code"i" is implemented by OCLC.

DEFAULT CODE: s

Code definitions

NOTE: See MARC 21 Format for Bibliographic Data (Leader/07 Bibliographic level) for code definitions not described below.

b Serial component part.

A serial bibliographic unit that is physically attached to or contained in another serial unit such that the retrieval of the component part is dependent on the physical identification and location of the host item or container. An example of a serial component part with corresponding host item is a regularly appearing column or feature in a periodical. The bibliographic record for a component part contains fields that describe the component part and data that identify the Host Item Entry (field 773). Since code "b" is not workable in all integrated library systems it is currently not used by CONSER. CONSER practice currently is to use code "s."

c Collection.

A made-up multipart group of items that were not originally published, distributed, or produced together. The record describes units defined by common provenance or administrative convenience for which is the record is intended as the most comprehensive in the system.

s Serial.

A publication in any medium issued in successive parts bearing numerical or chronological designations and intended to be continued indefinitely. Serials include periodicals, newspapers, annuals (reports, yearbooks, etc.), numbered monographic series, and the journals, memoirs, proceedings, transactions, etc. of societies.

i Integrating resource.

Code "i" identifies a bibliographic resource that is added to or changed by means of updates that do not remain discrete and are integrated into the whole. Integrating resources may be finite or continuing. Examples include updating loose-leafs and updating websites. The code will be implemented by OCLC no sooner than 2003. In the meantime, an interim practice will be used to code integrating resources (see B7 for further information).
