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. |
||||||||
Guidelines |
Each occurrence of the field requires one subfield ǂa to record which of the four modes of access the features that follow are intended to assist or adapt. Because the field is intended to describe both the sensory mode needed to access the content unassisted in subfield ǂa as well as any alternative sensory mode that enables one to access that content, any of subfields ǂb, ǂc, ǂd, and/or ǂe may follow any of the four sensory modes recorded in subfield ǂa. Multiple values from the same source vocabulary may be recorded in the same field in separate occurrences of the appropriate subfield. Terms from different source vocabularies are recorded in separate occurrences of the field. |

Subfields |
|||||||||
| ǂa Content access mode | Sensory mode that is required to access the content of the resource without using any of the assistive/adaptive features. The four sensory modes are textual, visual, auditory, or tactile. The assistive/adaptive features recorded in subsequent subfields may be in the same sensory mode as the contents or may be in an alternative sensory mode.
|
||||||||
| ǂb Textual assistive features | Textual assistive features and adaptations that enable access to the content of the resource. In this context, the textual mode refers only to written text (e.g., captioning, large print, transcript, etc.).
|
||||||||
| ǂc Visual assistive features | Visual assistive features and adaptations that enable access to the content of the resource. In this context, the visual mode refers to non-textual content that is accessed by sight (e.g., display transformability, high contrast display, sign language, etc.).
|
||||||||
| ǂd Auditory assistive features | Auditory assistive features and adaptations that enable access to the content of the resource through hearing (e.g., audio description, high contrast audio, etc.).
|
||||||||
| ǂe Tactile assistive features | Tactile assistive features and adaptations that enable access to the content of the resource through touch (e.g., braille, tactile graphics, etc.).
|
||||||||
| ǂ2 Source | Identification of the source of the term when it is from a controlled list. For more information about subfield ǂ2, see Control Subfields.
|
||||||||
| ǂ3 Materials specified | For information about subfield ǂ3, see Control Subfields.
|
||||||||
| ǂ6 Linkage | Data that link fields when non-Latin script is entered. This subfield is system supplied and does not appear in OCLC online displays. Do not manually add subfield ǂ6. For more information about subfield ǂ6, see Control Subfields. |
||||||||
| ǂ8 Field link and sequence number | For information about subfield ǂ8, see Control Subfields. |
