The local free-text call numbers based on a unique local system. You may also use field 099 for other call numbers that cannot be formatted for printing in the appropriate call number field. For example, use field 099 for complex LC call numbers that cause unit (zc) cards, or to format a Government Document number on two or more lines.
If you are creating new records, use the appropriate field (e.g.,
field 050 or
field 086) for call numbers, even if you repeat the same number in field 099 for printing.
Field 099 does not remain in the master record. It is retained in archive records, institution records, OCLC-MARC records, and exported records.

Subfields
‡a Classification number
Use a separate subfield ‡a for each printing line. You may use any combination of letters, numerals, punctuation, and special signs or symbols in subfield ‡a . You cannot cause a blank line to print within a local free-text 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 ‡a .
‡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 ‡a .
Printing
Field 099 prints in call number position. Field 099 overrides all other call numbers. The characters in each separate subfield (‡a , ‡e or ‡f) print on separate lines.
If the number of characters in any subfield exceeds the margin size, the print program drops the body of the card accordingly. The size of the left margin is two characters fewer than the first indention. If your profile establishes the first indention at ten, the margin size is eight.
