There are two basic types of numbering schemes:

1) consecutive or "whole" numbering, and

2)  volume numbers and internal numbers.

a. Consecutive numbering:

a single sequence of numbers that does not repeat ( FN4). This may occur at any level in the hierarchy. For examples of consecutive numbering at lower levels, see 8.3.2c. below. Examples

b. Volume numbers and internal numbers:

two or more part numbering schemes that consist of a consecutive volume number that changes on a regular basis (in most cases yearly) and an "internal" number that represents the individual issue and repeats with each new volume number. Example

In some cases, a year may serve as the volume number (see also CCM 8.5.5.). Examples

In some publications the word "year" or its equivalent in another language (e.g.,anno, año, or Jahrgang) substitutes as a caption for the volume number or is given in addition to the caption and volume number. Examples

c. Volume numbers and consecutive numbers appear in the same source:

When the second or subordinate level of numeric designation is consecutive, record both together as in 8.3.2b. above. Example

d. Alphabetic designations:

Occasionally, a publisher will use letters in place of, or in addition to, numbers. Examples

e. Numbered editions:

Numbered editions almost never constitute an edition statement for a serial (see Module 9). They either constitute the numbering or, in some cases, are ignored. Many serials, particularly directories, use the word "edition" (or its equivalent in other languages) in the numbering. When "1st edition" appears on a publication, determine first if it is the first issue of a serial, if the publication is a monograph that may be revised occasionally in subsequent editions (see Module 2), or if it is the first printing of that issue of a serial ( FN5). If the publication is cataloged as a serial, the word "edition" is given as part of the numbering.

Note: Do not confuse the use of the word "edition" with numbers or dates with an edition statement (field 250) that distinguishes publications that differ in contents, format, or scope, such as the "Northeast edition" and the "Southwest edition." In Figure 8.9., "Tenth edition" constitutes the numeric designation.

f. Parts:

When an issue of a serial is published in parts that are covered by the same bibliographic record, do not give the part in the designation, regardless of whether or not all of the parts are in hand at the time of cataloging.

In Figure 8.10., the numbering would be:

362 0# $a Nov. 20 & 21, 1989-

515 ## $a Issued in parts.
