Frequently Asked Questions when creating Name Authority Records (NARs) for NACO especially about LAC, NUC, & CIP
- When are headings based on CIP information that differ from the published item eligible for change?
- Do I need to obtain LAC verification for personal name or corporate name Canadian headings?
- How can we tell if a bibliographic record has been issued by LAC?
- Microform DCLM records are found in OCLC, e.g., DCLM NUC 87- ). Should we take these records into account when establishing new headings?
- May headings found on web sites or in CIP cataloging of national libraries (e.g., Australia, Brazil) be used as the authorized form?
- Is the National Union Catalog (NUC) considered authoritative in a case of conflicting dates?
- When a NACO cataloger finds an error on a NAR should the error be reported to the library that created it for correction?
- Should NACO catalogers wait for LC to give the go ahead before implementing rule changes, etc.?
All headings in the NAF are eligible to be changed by LC/NACO participants (within the parameters stated in DCM Z1). When a heading is found to be inaccurate regardless of the source of information, it may and should be changed (e.g., when a name or date is incorrect)
Headings based on information provided by a CIP t.p. or galley have a higher frequency of change because the published item often has a different form of usage on the chief source. This is not the same as changing a heading just to add a date or fuller form of name. If the heading in question is for a corporate name see questions 3 and 4 below.
As of August 2012 LC and PCC catalogers creating RDA name authority records are not required to search Library and Archives Canada (LAC) to determine the form of the authorized access point for either personal or corporate names.
Up until March 31, 2013, PCC Catalogers creating AACR2 name authority records should search for LAC NARs for Canadian authors by accessing the LAC authority file using the VIAF external link:
- 670 $a LAC in VIAF[date] $b (LAC hdg: ..... usage: ....., reference: .....)
Alternatively, you may search OCLC to find headings formulated by LAC on LAC-issued bibliographic records, or the Canadiana Authorities external link database.
Note that it is not necessary to search all of these sources. If the personal name heading is not found in the VIAF external link, NACO catalogers should create and contribute an NAR for the heading with a 675 citing the source checked. No further LAC verification is required (cf. DCM Z1, 1XX section).
Note that as of March 31, 2013 this AACR2-based LAC agreement will be discontinued.
LAC-issued bibliographic records contain the MARC organization code "CaOONL" or the OCLC code "NLC" in subfield $a and subfield $c of the 040 field.
No. Do not base headings on usage found in these records. All microform records with the prefix nuc87- should be ignored for AACR2 or RDA coding purposes. These records are part of a joint project of Association of Research Libraries and LC, the National Register of Microform Master Reconversion Project (NRMMRECon Project).
Headings found on web sites or in CIP information from national libraries may be used as long as the heading structure fits into the current policies and practices of AACR2 and the LCRIs, or RDA and the LC-PCC PSs, and the DCM Z1 procedures for NACO contribution.
Many national libraries use AACR2, but may not apply the LCRIs or the LC-PCC guidance found in the DCM Z1 in the formulation of their headings. It is important to examine the headings carefully before using these exactly as given. Information for fuller forms of names, dates, etc. may be used to formulate the heading in conjunction with the information on the chief source, etc. as instructed in AACR2, the LCRIs, RDA or the LC-PCC PSs.
Records in the printed NUC are as authoritative as any other source. Other reference sources should be consulted when the information in NUC is in doubt. (cf. FAQ on BFM)
That depends. Generally, in the interest of timeliness and the spirit of cooperation it is expected that if a cataloger finds an error in an authority record s/he is responsible for fixing the error(s) and reporting BFM. If the error is a repeated error and shows a pattern of misunderstanding of an instruction or “best practice” or is complex and may require extensive research, etc., in order to resolve, the NACO liaison may contact the liaison at the library listed in the 040 $c or $d of the NAR.
Yes. The Policy and Standards Division (PSD) at LC will post notices to the LC Cataloging and Acquisitions website with information on changes in documentation, practices, and policies that affect the NACO Program. Notices will also be disseminated via the PCCLIST informing NACO participants of when to implement changes, etc.
A parameter of the NACO program is that participants will adhere to the principles of AACR2 and the LCRIs, or RDA and the LC-PCC policy statements, and the DCM Z1 procedures when creating headings for contribution to the shared file. It is important to have all the documentation in synch so that an orderly implementation can take place. It is not acceptable to begin implementation of a rule change before the published text is available for all to use.
