Serial Numbering Basics

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 RDA as numbering. Each sequence is referred to as a “system of numbering ” 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 CONSER RDA serial description must have numbering given in two 588 fields, the “Description based on” note and the “Latest issue consulted” note. (If the first or last issue of the serial is in hand or known, numbering is also given in field 362.)

Serial numbering may include a numeral, a letter, any other character, or the combination of these with or without an accompanying caption (volume, number, etc.) and/or a chronological designation. Numeric and chronological information (designation and value) can be acquired from different sources and joined or pieced together to construct a complete (362) and (588) statement. The chronological designation may be pieced together from different sources, as may the numerical designation when it is clear that both parts constitute the numeric designation.
