NAME: Identification of Source in Field 015 (National Bibliography Number) and Field 017 (Copyright Registration Number) in the Bibliographic Format
SOURCE: Russian State Library
SUMMARY: This paper proposes defining subfield $2 (Source) in field 015 (National Bibliography Number) and field 017 (Copyright Registration Number) to identifying the source of the number. It also proposes making field 015 repeatable for multiple numbers from different sources.

PROPOSAL NO. 2001-03: Identification of Source in Field 015 (National Bibliography Number) and Field 017 (Copyright Registration Number) in the Bibliographic Format
Field 015 has been part of the MARC Bibliographic format since it was first developed in the late 1960s. The identification of numbers in field 015 has never been standardized. In the past, LC made use of a list of prefixes which helped to identify the country in whose national bibliography a number appeared, but the list was never publicly available and is no longer maintained. National libraries usually collect some materials from other countries, particularly when the items relate to the collecting country (e.g., books about France published outside of France would be of interest to the collections of the National Library of France). The inclusion of these materials in a national library database gives rise to the need to record multiple national bibliography numbers, from different sources, in the same record. At present, these numbers must be recorded in a single occurrence of field 015.
Field 017, on the other hand, can be repeated for multiple numbers from differing assigning agencies. Unfortunately, it is only possible to identify a number by the assigning agency, not the source publication or listing. The Russian State Library (RSL), a MARC 21 user, has found this to be inadequate, in cases where they prefer to record the resource in which the number appears (e.g., a legal deposit listing). Legal deposit numbers are particularly important because legal deposit publications are often the most authoritative sources of information available about the country's bibliographic production.
The changes suggested in will allow the RSL to replace a locally-defined data element with a standard MARC 21, non-repeatable subfield $2 that can be used and understood by all MARC 21 users. The proposal also suggests making field 015 repeatable for multiple numbers from different sources since it is not desirable to repeat subfield $2 in the same field.

Subfield $2 contains a code that identifies the source of the National Bibliography Number in subfield $a. The source of the code is the MARC Code Lists for Relators, Sources, Description Conventions, that is maintained by the Library of Congress.
