Definition

The physical description of the item including the extent of the item and its dimensions. Use field 300 also for other physical details of the item and information concerning accompanying material.

For information on punctuation, see the Punctuation section below.

Guidelines

In records formulated following cataloging rules based on International Standard Bibliographic Description (ISBD), a relationship exists between prescribed ISBD punctuation and the identification of specific subfield data. RDA and AACR2 bibliographic records in WorldCat generally follow ISBD principles for description and punctuation.

WorldCat accommodates both RDA and AACR2 bibliographic records. Prefer use of RDA forms when adding or editing elements of field 300, e.g., spelling out non-transcribed abbreviations, except those that represent measurements of time and physical dimensions.

For guidance on describing and encoding the attributes of audio recording carriers, see “Supplement 1” of the Music Library Association’s Supplements to Best Practices for Music Cataloging Using RDA and MARC21.

Subfields

Descriptions of subfields ǂa, ǂb, ǂc, and ǂe and examples are listed in categories.

ǂa Extent

The extent of the item. In records formulated according to ISBD principles, subfield ǂa includes all data up to and including the next mark of ISBD punctuation, e.g., a colon, a semicolon, or a plus sign, whether included or not.
