Module 8. Numbering (Fields 362, 500)

Most serials bear numbers, letters, and/or dates that distinguish one issue from another. The sequence of numerals, letters, and/or dates that appear on a serial is referred to collectively in AACR2 as "numbering." Each sequence is referred to as a "numbering system" and some serials have more than one system of numbering. Numbering is one of the most unique and important features of serials because it provides an identification for each issue that allows for recording and retrieval of the issue. With the exception of unnumbered series, every AACR2 serial record must have numbering given in either field 362 (1st indicator "0") or field 500 ("Description based on" note). In some cases, this data is supplied. When information is known about the first or last issue but the issue is not in hand, the information may be given in field 362 (1st indicator "1").

This module will discuss:

The relationship between field 362 and the "Description based on" note (field 500)
