DCM Z1: 642 Series Numbering Example
LC series practice: As of June 1, 2006, LC does not create or update SARs.
PCC series practice: Transcription of the series statement is mandatory if applicable. Searching for series authority records, tracing the series, and the creation and maintenance of series authority records are optional.
Consult RDA 24.6 and the associated LC-PCC PS concerning choice of numbering designation.
Determine the form of numbering from the item in hand (not necessarily the first item of the series) and then use that form in tracing all items in the series. When reestablishing a series, change any subfield $v forms in access points in existing analytic record that don't match the form in the 642 field.
If the only number found on the item is the number in the series statement within the CIP data, ignore that number and consider the series to be unnumbered.
If at the time of reestablishing a series, analytic records in the database show that the series is both numbered and unnumbered but the item in hand is unnumbered, determine the form of number to be used in the tracing from the records in the database and record the earliest number in the 642 field. Also add in a 670 field the citation of the analytic bibliographic record on which the form of number is based; include the number in the parenthetical data in the subfield $b.
If the analytic being cataloged is a multipart item that represents more than one volume in the series (e.g., the two volumes of the multipart item are numbers 17 and 18 of the series), record only one number in the 642 field; do not use a sequence of numbers.
When an analyzable multipart item is classified with another series (646 $a = m), the number recorded at the end of the call number in the 050 field will not be the number found in the 642 field. The number found in the 050 field is the number of the "other series" found on the item in hand. (See DCM Z1 050.)
When wording such as "new series" has been supplied in brackets with the numbering in the bibliographic record 4XX subfield $v (cf. RDA 2.12.9.6), include the brackets in the 642 field being added to the SAR.
642 ## $a [new series], no. 1
Serial catalogers: Include the 642 field even though subfield $v usually doesn't appear in 4XX/8XX of serial analytic records.
Recording national-level and PCC local decisions for form of numbering:
The national-level decision for form of numbering is to be followed by those libraries creating PCC records. The MARC 21 organization code used for this national-level decision in subfield $5 is "DPCC" (PCC = Program for Cooperative Cataloging). PCC participants should include the national-level and local decisions in SARs according to the following guidelines.
PCC participants: new SAR
(1) Always include the national-level decision for form of numbering for a numbered monographic series, multipart item, or other series (serial) regardless of your local tracing decision. Determine the form of number according to usual rules/policies.
642 ## $a [form of number] $5 DPCC
(2) If your local tracing decision is to trace, optionally add your MARC 21 organization code as the last subfield $5 in the one 642 field.
642 ## $a [form of number] $5 DPCC $5 CoDU
PCC participants: existing SAR
(1) If the national-level decision is not in the SAR, it may be added to the record.
(2) If your local tracing decision is to trace, optionally add your MARC 21 organization code as the last subfield $5 in an already-existing 642 field. NOTE: Only one PCC participant may include a form of numbering decision in an SAR. If a 642 field isn't present, optionally add the field with your MARC 21 organization code in subfield $5.
642 ## $a [form of number] $5 DPCC $5 CoDU
642 ## $a [form of number] $5 DPCC $5 DLC $5 IRA
642 ## $a [form of number] $5 DLC $5 IRA
642 ## $a [form of number] $5 WaU
[Examples represent single fields in different SARs; "DPCC" already in the first and second SARs.]
