EAD Tag Library for Version 1.0


EAD Elements: <extent> Extent

Description:

A <physdesc> subelement for information about the quantity of the materials being described or an expression of the physical space they occupy. Includes such traditional archival measurements as cubic and linear feet and meters; also includes counts of microfilm reels, photographs, or other special formats, the number of logical records in a database, or the volume of a data file in bytes.

Repeat the element when more than one type or unit of extent is provided, such as, when both linear feet and quantity of containers are given. Use the UNIT attribute to indicate the measurement unit, e.g., "bytes" or "cubic meter."

Use the <dimension> element when it is necessary to specify the size of the archival materials being described, for example, height and width.

The <extent> element is comparable to ISAD(G) data element 3.1.5 and MARC field 300, subfield a.

May contain:

#PCDATA, abbr, archref, bibref, emph, expan, extptr, extref, lb, linkgrp, ptr, ref, title

May occur within:
