Definition

Information relating to the version of a resource, preferably taken from a controlled vocabulary.

For information on punctuation, see the Punctuation section below.

Guidelines

This field is intended for standardized identification, preferably using a controlled vocabulary, of the pre-publication, published, and post-publication versions of resources that include but are not limited to books, chapters of books, technical reports, conference papers, and articles in both tangible and digital form. The terms used in this field specifically identify and distinguish the various states in which a resource may exist. These include such states as author’s originals, drafts, submitted manuscripts, proof versions, corrected versions, accepted manuscripts, and preprints. Field 251 does not include numerical version designations or statements of responsibility.

Use field 250 for edition statements that are transcribed from the resource or that are supplied by the cataloger under the provisions of RDA 2.5.1.4 or AACR2 LCRI 1.2B4, for manifestations known to contain significant changes or differences from other editions.
