Authentication Code (042)

Field 042 contains one or more codes that represent different levels of authentication of CONSER records. Codes "lc", "nlc", "nsdp" and "isds/c" represent specific agencies or Centers of Responsibility. Codes "lcd", "msc", and "lccopycat" reflect the status of name headings in the record. Codes "pcc", "msc", and "lccopycat" reflect the status of name headings in the record. Codes "lc" and "lcd" were superseded by the code "pcc" May 1, 2009 but remain valid in existing records.

Beginning May 1, 2009 all CONSER institutions use the authentication code "pcc" in place of codes "lcd" and "lc" in records newly authenticated and distributed as part of the CONSER Program. The code is used in records for both serials and integrating resources.

Code "pcc" indicates a Program record where the description meets PCC standards and authority records exist for all headings. In a CONSER standard record, code "pcc" signifies that the CONSER descriptive elements have been verified by an authenticating CONSER participant. Name and series headings have been checked against the LC/NAF and authority records have been created if they did not already exist. Subject headings are checked for authorized forms or combinations supported by the relevant authority.

While CONSER catalogers are expected to authenticate most of the records they create or maintain, they are not required to authenticate every record. Records that are authenticated must conform to the following:

Creation of new bibliographic descriptions are based on Resource Description and Access (RDA), the LC-PCC Policy Statements inRDAToolkit, and other CONSER and PCC documentation.

Headings for names and series used in CONSER records are given in RDA form, as of the adoption of RDA

Classification, when given, is based on standardized schemes. Subject headings, when given, are based on standardized lists. Subject headings newly input to CONSER records are at the appropriate level of specificity, are currently valid, and are properly constructed and tagged.

CONSER records are created cooperatively; therefore, information in records created by CONSER members is accepted by other members, unless the information is obviously erroneous. When questions arise, CONSER catalogers routinely consult with one another to determine the appropriate action.
