If a book includes only a part or section of a larger work, the number of that part or section may be entered in $n. Numbering includes letters as well as numbers, and any other designation of sequence.

¶ subfield p - Name of part/section of a work

¶ Verify Method
- FULL - Full compares the full verify string up to the verify length.
- PARTIAL - Partial truncates the compare strings to the shortest string, then does a full compare. "The fox in the hound" in one record, "The fox" on the other record : both truncated to "The fox" and compared.
- WITHIN - Withing searches each compare string truncated at verify length against the full un-truncated string of the other field. "Cat" will ind a potential match on "The cat in the hat."
¶ Normalization
- NACO/CJK retains spaces and subfield delimiters.
- FULL is NACO normalization with all spaces and subfield delimiters removed.
