Definition

This field uses controlled vocabularies to convey information about textual, visual, auditory, and/or tactile modes of access to the primary and/or secondary contents of a resource. These sensory modes of access may be either the chief means of access (e.g., large print) or alternatives to the chief means of access (e.g., closed captioning in a video recording). Accessibility content may include, but is not limited to, accessible labels, audio description, captioning, image description, sign language, and subtitles. Accessibility content does not include subtitles in a language different from the spoken content. Free-text description of the accessibility content in human-readable form may be recorded in field 532.

For information on punctuation, see the Punctuation section below.
