Definition

Call numbers based on National Library of Medicine (NLM) or Library of Congress (LC) classification schedules and assigned by any library other than NLM. Field 096 is not part of the standard MARC 21 Bibliographic format. If you use LC classification for all materials, use field 050 or field 090.

Guidelines

If you are transcribing LC or NLM copy, use field 060 for the NLM-assigned call number. Field 096 is not retained in the WorldCat record if field 060 contains a call number. Field 096 is retained in exported records and records delivered via other services.

If you assign a National Library of Medicine classification number according to the NLM class schedules, prefer field 060 with 1st indicator blank, 2nd indicator 4. If the classification portion of your number does not conform to the NLM class schedules, use field 099.

Multiple call numbers

Certain classification choices are recognized to be local decisions. Multiple call numbers in the same classification scheme in a WorldCat record may be appropriate under certain circumstances. For more information, see 050-099 Introduction to Call Numbers.

Subfields

 
ǂa Classification number

The class number portion or the complete call number. Enter spaces in the NLM call number to conform to NLM formatting practice. Enter one space to indicate each new line needed in label displays.

096     WQ18
ǂb Item number

The item number portion of the NLM call number. You may enter the complete call number in subfield ǂa instead.

Your use of subfield ǂb in the 060 and 096 fields affects the processing and use of OCLC-MARC records.

The National Library of Medicine (NLM) uses the Cutter-Sanborn Three Figure Author Table (1969) when assigning Cutter numbers, although NLM supplies cutter numbers only for material shelved in their reference or History of Medicine collection. OCLC recommends that health science libraries consider using this same table for assigning Cutter numbers.
