040  Cataloging Source (NR)

Definition

The OCLC symbol, the MARC organization code, or the name of the organization(s) that created the original record, assigned MARC content designation, transcribed the record into machine-readable form, and/or modified an existing MARC record. For details on specific symbols and codes, see Directory of OCLC Libraries, MARC Code List for Organizations, which also includes links to Canadian, United Kingdom, and German MARC Organization Code lists, or Symbols and Interlibrary Loan Policies in Canada.

Field 040 may also contain data that identify the descriptive cataloging rules and language of cataloging used to create the record.

Guidelines

Historically in WorldCat the absence of subfield ǂb in field 040 has indicated that English is the language of cataloging. OCLC now prefers always coding this element.

Note: The preferred order of 040 subfields is: ǂa, ǂb, ǂe, ǂc, ǂd.

Field 040 has a logical relationship to the fixed field element Srce. When you validate a record, the system checks information in Srce and field 040 subfield ǂa to ensure a logically correct combination of data. The system checks for the following combinations of data in Srce and field 040 subfield ǂa:

If the system finds an incorrect combination, it displays an error message. Correct the error and validate the record.

Each time you edit a record and produce or update without replacing, the system verifies that your OCLC symbol is the last subfield ǂd in field 040. If it is not, the system supplies subfield ǂd and your symbol. It will display for that editing session, but it is not retained in the WorldCat record. However, it is retained in exported records and records delivered via other services.

If institution A edits a record input by institution B, and then updates, the system supplies the symbol for institution A in the last subfield ǂd in field 040. If the record is then reformatted, the system displays the symbol and institution A's changes. The symbol and institution A's changes are not added to the WorldCat record.

If institution A edits a record input by institution B, and then replaces the WorldCat record, the changes and symbol for institution A are added to the WorldCat record. Do not attempt to replace a WorldCat record after editing and updating in the same session.

The system also replaces the WorldCat record and adds subfield ǂd when:

• OCLC changes WorldCat records manually or programatically.
• Participants of cooperative programs such as BIBCO, CONSER, Enhance, etc., upgrade and change records.
• Member institutions upgrade minimal-level cataloging, make changes as part of the Expert Community, or perform database enrichment, including the addition of call numbers and subject headings to records.

If the modifying institution's symbol is already the last symbol in field 040 subfield ǂd, the system does not repeat the subfield ǂd.

If you are inputting original cataloging on a workform or new record, enter blank, c, or d in Srce. OCLC users at authorized national bibliographic agencies enter blank. BIBCO and CONSER participants, except for those at authorized national bibliographic agencies, enter c on records created as part of those programs. In all other cases, enter d.

Data entered manually in field 040 subfield ǂa must be entered exactly, including upper- or lowercase letters. If a symbol is entered manually, the system does not uppercase any letters entered as lowercase. The one exception is the symbol DLC that represents the Library of Congress if that is the only data entered in subfield ǂa.

Generally, transcribe cataloging copy exactly as found in the original source. However, you may make some modifications to accommodate online cataloging and/or to modernize old cataloging. If you make a change, you should enter your OCLC symbol in subfield ǂd.

If you are entering LC copy or any other LC cataloging, enter blank in Srce and DLC in field 040 subfield ǂa.

If you transcribed the cataloging exactly, enter blank in MRec. If you modified the cataloging, enter the appropriate code in MRec and enter your OCLC symbol in field 040 subfield ǂd.

Treat LC copy with the legend Printed for (e.g., Printed for Card Division) as Library of Congress cataloging.

If LC copy has Shared cataloging for DNAL (National Agricultural Library) in the lower left corner on LC copy, enter blank in Srce and AGL in field 040 subfield ǂa.

For LC copy that has Shared cataloging with DNLM (National Library of Medicine) in the lower left corner on LC copy, enter blank in Srce and DNLM/DLC in field 040 subfield ǂa.

If you transcribed the cataloging exactly, enter blank in MRec.

LC copy that is based on cataloging of another institution carries the name of the other institution in the lower left corner.

If you are transcribing such cooperative cataloging, enter the OCLC symbol corresponding to the name in field 040 subfield ǂa. If the OCLC symbol cannot be readily determined, enter the name in field 040 subfield ǂa exactly as it is on the copy. Enter c in Srce. Do not enter the words Library of Congress.

LC cooperative cataloging with the National Agricultural Library or the National Library of Medicine contains designations such as: Library, US Dept. of Agriculture, US Nat'l. Agr. Lib., or US National Library of Medicine. Enter c in Srce if you are transcribing such copy.

If you transcribed the cataloging exactly, enter blank in MRec. If you modified the cataloging, enter the appropriate code in MRec and enter your OCLC symbol in field 040 subfield ǂd.

[Enoch Pratt Free Lib. appears on the copy; Original cataloging by MDB and entered by MDY as an English language record using AACR2]

Modified transcription, cooperative cataloging:

If you are transcribing LC cooperative cataloging that includes an NLM or NAL classification number, enter the number in the appropriate call number field, field 060 or field 070. Do not enter any other classification or call number. The medical-type call number that may appear following US Army Medical Library is not an NLM call number. Do not enter this number.

For example, if LC copy includes the legend, Brown Univ. Library BL1453, then enter:

Srce:			c
MRec:			[or other applicable value]
040			RBN ǂb eng ǂc IAY
[Original cataloging by RBN and entered by IAY as an English language record using AACR2]

Enter blank in Srce and NLM in field 040 subfield ǂa. If you transcribed the cataloging exactly, enter blank in MRec. If you modified the cataloging, enter the appropriate value in MRec, and your OCLC symbol in field 040 subfield ǂd.

If you are transcribing typewritten National Union Catalog (NUC) copy, enter the OCLC symbol corresponding to the first MARC organization code that appears on the copy in field 040 subfield ǂa. If the OCLC symbol cannot be readily determined, enter the first MARC organization code that appears on the copy in field 040 subfield ǂa. Enter d in Srce.

If you transcribed the cataloging exactly, enter blank in MRec. If you modified the cataloging, enter the appropriate code in MRec and enter your OCLC symbol in field 040 subfield ǂd.

Modified transcription, other non-original cataloging:

If the first holding code on the NUC copy is DLC, DNLM, or DNAL, treat the cataloging as your own original cataloging, not as LC, NLM, or DNAL (National Agricultural Library) cataloging.

Treat non-LC, non-NLM, or non-original cataloging as your own original cataloging. Do not add your symbol in subfield ǂd.
