Definition

Call numbers based on LC classification schedules, but assigned locally. If you are transcribing LC copy, use field 050 for the LC-assigned call number. Use field 055, field 060 or field 070 for call numbers based on LC classification schedules but assigned by the Library and Archives Canada (NLC), the National Library of Medicine (NLM) or the National Agricultural Library (NAL).

Records may contain field 050 and field 090, but only if field 050 is a word or phrase (e.g., PAR, Newspaper, UNC, or NOT IN LC). Field 090 is not retained in the master record if field 050 contains a call number. It is retained in archive records, institution records, OCLC-MARC records, and exported records.

If you assign a Library of Congress classification number according to the LC class schedules, use field 090 or field 050 with indicators "14". If the classification portion of your number does not conform to the LC class schedules, use field 099.

Multiple call numbers

 Certain classification choices are recognized to be local decisions. For example, if one user has chosen to class together a monographic series and another library classes it separately, multiple call numbers in the master record may be appropriate. Multiple call numbers are allowed in these circumstances:
 
  • Classed together number vs. classed separately number for monographic series
  • Literature number vs. PZ number for fiction
  • Bibliography number vs. subject number
  • LC minimal number vs. member call number
  • Geographic classification number vs. subject classification number for maps and atlases
  • LAW number vs. actual K class number

Subfields
‡a Classification number The class number portion of the locally assigned call number.
‡b Local Cutter number The item number portion of the locally assigned call number.
‡e Feature heading A feature heading from a classified catalog. Data in subfield ‡e print on cards and display in label displays as if they were in subfield ‡b.
‡f Filing suffix A filing suffix from a classified catalog. Data in subfield ‡f print on cards and display in label displays as if they were in subfield ‡b.

Printing

 Data in subfields ‡e and ‡f print as if they were in subfield ‡b.
K schedules

OCLC provides a special class K option for incomplete class numbers. You may assign a call number that consists of the alphabetic portion of the projected class number (e.g., KM or KR) followed by an item number.

If you are entering such a call number, enter 0 following the class letters. The print program prints the class letters and the remainder of the call number but suppresses the 0. Your profile determines whether a blank line intervenes between the class letters and the Cutter number.

If the classification number is complete (e.g., KD5110 or KF4558), treat the call number as a complete call number.

If a call number in field 050 or field 090 has class letters only (no 0 or other numeral following the class letters), a zc card results.
