6G1. Give the numbering of the publication within the series in the terms given in the publication. Use abbreviations (see AACR 2, 1988 revision, Appendix B) and substitute Arabic numerals for other numerals or spelled out numbers (see AACR 2, 1988 revision, Appendix C).

6G2. Multivolume publications

[PREAMBLE. Expanded/split volumes. looseleafs that start as single-volume publications but are later expanded/split into several volumes may or may not be numbered as the result of expansion. If the publication is in a series (usually a larger multipart publication), the series numbering applied to the expanded volumes is usually dependent upon the publishing pattern of the larger work and the facility with which the series numbering of the expanded volumes can be fit within the already existing publishing pattern. In some cases the expanded volumes may be numbered in their own right, e.g., "volume 1," "volume 2," etc., with series numbering expanded as, e.g., "volume 9A," "volume 9B," etc. Equally as often the item, although expanded into several volumes (binders), carries no volume numbering per se and only the numbering of the series is expanded, e.g., "volume 2," "volume 2A," "volume 2B," etc.

For looseleaf publications in a series (usually a larger multipart publication), the Library of Congress lists the series numbers applied to each part (including expanded volumes) explicitly (not in compressed form) in the series statement for as long as the looseleaf is being published, e.g., ; v. 15A,, 15B, 15C not ; v. 15A-c. This is because of the special numbering characteristics of some looseleaf publications. From the point of view of bibliographic description, the series numbering could easily be recorded in conventional form. However, taking into consideration the bibliographic control of the expanding volumes, their recording in the extent portion of the physical description area, as well as the recording of the holdings in the shelflist (where the unnumbered items, presently assigned numbering, are best controlled by identifying each volume also by the series number), it is best not to use a compressed notation in the series statement.]

If the parts of a multivolume item are separately numbered within a series, give the first and last numbers if the numbering is continuous; otherwise, give all numbers (14).

6G2. Example 1

Optionally, for expanded active looseleaf publications, record volume numbers in detail. (LC applies the option.)

6G2. Example 2

If the publication has a designation other than a number, give the designation as found. Exception: Substitute Arabic numerals for asterisks (without the use of square brackets).
