EAD Elements

<controlaccess> Controlled Access Headings


A wrapper element that designates key access points for the described materials and enables authority-controlled searching across finding aids on a computer network. Hundreds of names and subjects can appear in a finding aid. Prominence can be given to the major ones by bundling them together in a single place within the <archdesc> or within a large Component <c> and tagging them with <controlaccess>.

The <controlaccess> element designates terms comparable to those found in the 1xx, 6xx, and 7xx fields of MARC catalog records. Finding aid searches limited to the <controlaccess> element and its subelements will improve the likelihood of locating strong sources of information on a desired subject, because access terms will have been entered in a consistent form across finding aids, and also because only the most significant terms are likely to have been selected for encoding.

Although names and terms from locally controlled vocabularies are permissible, the <controlaccess> subelements (<corpname>, <famname>, <function>, <genreform>, <geogname>, <occupation>, <persname>, <subject>, and <title>) should come from national or international vocabularies whenever they are available to enable searches in information systems that include multiple finding aids, or finding aids and bibliographic records from many institutions.

These subelements have SOURCE attributes to specify the vocabulary tool from which the heading is taken and RULES attributes to specify the descriptive rules by which it has been formulated. The attribute AUTHFILENUMBER can be used to identify an authority file record that provides additional information about a heading and includes cross references. The ROLE attribute can be used to specify such factors as whether a heading is for the creator of the materials, the subject of the materials, or both.
