Form Subdivisions (|v, $v) in Subject Headings

The Library of Congress began using subfield v (|v or $v) for form subdivisions in subject headings effective February 17, 1999. Below is a list of form subdivisions (i.e., those that describe the form of an item, not its subject matter) from Free-Floating Subdivisions: an Alphabetical Index, 16th ed. Topical subdivisions will continue to be coded in subfield x (|x or $x).

Library of Congress practice for multiple subdivision strings is indicated by the inclusion of the MARC subfield codes (e.g., x-y-v). Form subdivisions that can be subdivided geographically are indicated with an asterisk.

Note on usage, from Subject Cataloging Manual: Subject Headings, H.1075, 1.d: "Code a form subdivision as an |x subfield when it represents a form that the item is about. This often occurs when a subdivision that is normally a form subdivision is followed by another form subdivision." For example:

Mississippi |v Maps (for actual maps of Mississippi) but
Mississippi |x Maps |v Bibliography (for a bibliography of Mississippi maps)
