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.

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.

1st Indicator
