Identification of PCC records

revised Aug. 22, 2001

This memorandum states the conventions to be applied in identifying records created/upgraded by PCC/BIBCO. The accompanying table Identification of PCC-Associated Records Post March 3, 1996 has been prepared to ensure that all the new and upgrade conditions that can obtain under PCC have been taken into account. The conventions are similar to those applied under the National Coordinated Cataloging Program (NCCP), but have been simplified as they relate to upgraded LC-created encoding level 5 in-process records (called in LC Initial Bibliographic Control records and referred to hereafter and in the table as an "IBC record").

The following notation is used in stating the conventions of identification:

Note: In the examples content designation is in MARC 21 notation except, for clarity, each subfield is preceded and followed by a space.

1. OCLC TREATMENT OF LC IBC RECORDS

The treatment of LC IBC records in OCLC depends upon the load source and the conditions encountered at the time of load as follows:

1.1 if an incoming IBC record issued by LC does not match an existing record, it is loaded if from an overseas office and retains its identity as an LC-issued record:

Ldr/17 = 5
008/39 = #
040 ## $a DLC $c DLC
042 ## $a lcode

1.2 if an incoming IBC record issued by LC matches an existing record, it is processed but loses its identity as an LC-issued record:

Ldr/17 = [value in the matched record]
008/39 = d
040 ## $a CAL $c TRL $d DLC

1.3 if an IBC record is upgraded to full in a local system and subsequently loaded into OCLC, the record retains its identity as an LC-issued record but the symbol of the upgrading library is in the $c subfield of 040:

Ldr/17 = #
008/39 = #
040 ## $a DLC $c TRL

2. IDENTIFICATION OF PCC CREATED/UPGRADED RECORDS (NON-CIP)

2.1 Newly created record.

Ldr/17 = # (full); 4 (core)
008/39 = c [# if created by a National Bibliographic Agency]
040 ## $a CAL $c TRL
042 ## $a pcc

2.2 Upgraded non-LC record/Matched LC IBC record in OCLC. Note that this category includes LC-issued IBC records from overseas offices that match existing records in OCLC and lose their identity as an LC-issued record as described in 1.2 above.

Ldr/17 = # (full); 4 (core)
008/39 = c
040 ## $a CAL $c TRL $d UPL
042 ## $a pcc

2.3 Upgraded LC IBC record (done by PCC participant working in LC system). Note that this category includes LC-issued IBC records that do not match existing records in OCLC as described in 1.1 above.

Ldr/17 = #
008/39 = # [change in practice: do not change to "c" as under NCCP]
040 ## $a DLC $c DLC $d UPL
[change in practice: do not change $a subfield to DLC/UPL as under NCCP]
042 ## $a pcc

2.4 Upgraded LC IBC record (overseas office). Note that this category includes LC-issued IBC records that do not match existing records in OCLC as described in 1.1 above.

Ldr/17 = #
008/39 = # [change in practice: do not change to "c" as under NCCP]
040 ## $a DLC $c DLC $d UPL
[change in practice: do not change $a subfield to DLC/UPL as under NCCP]
042 ## $a lcode $a pcc

2.5 Upgraded LC IBC record loaded to OCLC from local system. Note that this category includes upgraded IBC records described in 1.3 above.

Ldr/17 = #
008/39 = # [change in practice: do not change to "c" as under NCCP]
040 ## $a DLC $c TRL
[change in practice: do not change $a subfield to DLC/UPL as under NCCP]
042 ## $a pcc
[if IBC record from LC overseas office, 042 contains $a lcode $a pcc]

3. IDENTIFICATION OF LC RECORDS

3.1 Full. Identification of LC full records remains the same:

Ldr/17 = #
008/39 = #
040 ## $a DLC $c DLC

3.2 Core (non-CIP). To draw attention to core records, those created by LC also contain "pcc" in an 042 field:

Ldr/17 = 4
008/39 = #
040 ## $a DLC $c DLC
042 ## $a pcc

3.3 CIP (intended to be core). While in a CIP state (Ldr/17 = 8), "pcc" in 042 signals that the record is intended to be core.

Ldr/17 = 8
008/39 = #
040 ## $a DLC $c DLC
042 ## $a pcc

3.4 Core (formerly CIP). The identification is now the same as for 3.2 above.

Ldr/17 = 4
008/39 = #
040 ## $a DLC $c DLC
042 ## $a pcc

4. IDENTIFICATION OF PCC/UPGRADED CIP RECORDS IN OCLC

4.1 CIP (intended to be full). Record after being loaded into OCLC:

Ldr/17 = 8
008/39 = #
040 ## $a DLC $c DLC

4.2 Full (formerly CIP intended to be full). Record after upgrade to full by PCC participant:

Ldr/17 = #
008/39 = # [do not change to c]
040 ## $a DLC $c DLC $d UPL
042 ## $a pcc [added by PCC participant]

4.3 CIP (intended to be core). Record after being loaded into OCLC:

Ldr/17 = 8
008/39 = #
040 ## $a DLC $c DLC
042 ## $a pcc

4.4 Core (formerly CIP intended to be core). Record after upgrade to core by PCC participant:

Ldr/17 = 4
008/39 = # [do not change to c]
040 ## $a DLC $c DLC $d UPL
042 ## $a pcc [in CIP state, LC indication that record is intended to be core; after upgrade in OCLC, "coreness" now indicated by Ldr/17 = 4; 042 = pcc now is signal record upgraded by a PCC participant]

4.5 Full (formerly CIP intended to be core). Record after upgrade to full instead of core by PCC participant:

Ldr/17 = # (full)
008/39 = # [do not change to c]
040 ## $a DLC $c DLC $d UPL
042 ## $a pcc [in CIP state, LC indication that record is intended to be core is now rendered moot by upgrade to full in OCLC; 042 = pcc is signal record upgraded by a PCC participant]
