24X Subfield $n - Number of part/section of a work: [242, 245, 246, 247]

Subfield $n contains a number designation for a part/section of a work used in a title. Numbering is identified as an indication of sequencing in any form, e.g., Part 1, Supplement A, Book two. In music titles, the serial opus, or thematic index number are generally not contained in subfield $n.

In records formulated according to ISBD principles, subfield $n data follows a period ( . ). Multiple alternative numberings for a part/section are contained in a single subfield $n.

Subfields $n and $p are repeated only when following a subfield $a , $n, or $p. If a title recorded in subfield $b or $c includes the name and/or number of a part/section, those elements are not separately subfield coded.
