Identification and authentication of BIBCO records
The purpose of this document is twofold: To assist all catalogers in
the identification of BIBCO program records, and also to provide guidance
for original catalogers upgrading in-process, CIP, minimal level, and
non-PCC records to a BIBCO record, either in the bibliographic utilities
or in local systems. This chart should be considered for quick reference
only. For more detailed instructions about creating BIBCO records, catalogers
should refer to the BIBCO Participants' Manual or
available via Cataloger's Desktop and/or other appropriate documentation.
There are three tables addressing different conditions a cataloger may
encounter. The first details how to identify records cataloged by LC,
including core and full CIP records. The second and third tables address
the process of authenticating non-PCC records in either the bibliographic
utilities or in local systems. Some explanatory notes follow Table 3.
Please refer to them for further details on the information below.
Tables:
Table 1. Identification of records for items
cataloged by LC
Table 2. Authenticating non-BIBCO records in the Utilities
Table 3. Authenticating non-BIBCO Records in Local Systems
Notes on the Tables
Abbreviations used in the tables
CAL = Cataloging library (as represented by MCLO symbol)
IBC = Initial Bibliographic Control (LC term used for item in process)
MCLO = MARC Code List for Organizations (formerly NUC symbol)
TRL = Transcribing (inputting) library (as represented by MCLO symbol)
UPL = Upgrading library (as represented by MCLO symbol)
Table 1. Identification of records for items
cataloged by LC
Use this table to identify various types of records created by or in
collaboration with LC.
Note the absence of an authentication code (042=pcc) in full records
(CIP or updated CIP) that are cataloged by LC alone. LC uses the authentication
code only in its core records or on records created in collaboration
with another agency (e.g., NLM.)

Table 2. Authenticating or upgrading records
in the utilities
Use this table as a quick reference document for selected MARC fields
when updating various kinds of records encountered in the utilities.
The activity column lists the action that the cataloger is taking. The
Condition column lists each step in the upgrade process, with the corresponding
rows and columns for that condition giving a view of the Cat Src, Enc
Lvl, 040, and 042 codes at various stages in the update.

Notes on the tables
- Content designation is in MARC 21 notation except,
for clarity, each subfield is preceded and followed by a space; # =
blank, $ = delimiter.
- In the examples of 040 fields, the appropriate subfield $d for the
condition being illustrated is shown immediately following subfield
$c. In some cases, particularly for records in OCLC, there could actually
be intervening $d subfields. In the internal OCLC record the symbols
in 040 are in the OCLC form; upon export, they are translated into
the MARC 21 Code List for Organizations form (except when
using Z39.50, in which case they remain in the OCLC form).
- When the 042 column shows multiple codes, they are carried in the
record in repeated $a subfields in a single 042 field (e.g., $a lcode
$a pcc).
- Changing encoding level to blank and changing 042 in the OCLC system
requires National Level Enhance.
- In 1997 008/39 (Cataloging source) value "blank" was
redefined from "Library of Congress" to "National
bibliographic agency." NLM switched to using blank at the beginning
of 2000. The guidelines for identifying PCC records and those issued
by the Library of Congress are now as follows:
- records created by PCC libraries:
008/39 (Cataloging source) is either "c" or "blank" (blank
is used by any national bibliographic agency, e.g., the National Library
of Medicine);
042 is "pcc";
- full level original cataloging records created by LC:
no explicit PCC identification (008/39 = blank; no 042);
- core level original cataloging records created by LC:
no explicit PCC identification; 008/39 = blank; 042 = pcc (Ldr/17 (Encoding
level) = 8 for records in a CIP state and changed to 4 upon completing
the cataloging with item in hand); use of pcc in 042 is not to identify
a PCC record per se but to identify unambiguously records that are
core level or are intended to be core level (when in a CIP state).
- Since the 008/39 value for any national bibliographic agency is now
blank, that should be the value used in any PCC-related record as follows:
- any new record created by a national bibliographic agency that
is also a PCC member;
- any already existing record originally created by a national
bibliographic agency, whether a PCC member or not, that is now
upgraded to a PCC record (042 = pcc) by a PCC library.
