Subfields |
|
| ǂa Category of material |
A one-character alphabetic code that indicates the category of material to which the item belongs is tactile material.
| f |
Tactile material. Item is tactile material, which is intended to be read by touch. |
|
| ǂb Specific material designation |
A one-character alphabetic code that describes the special class of material (usually the class of physical object) to which an item belongs.
| a |
Moon. The material uses a line based tactile code in which many of the letters are simplified versions of the printed alphabet. |
| b |
Braille. The material uses a system of tactile code in which letters, numerals, and punctuation are made of raised dots distinguishable by the fingers. |
| c |
Combination. The material uses two or more of the other defined types. |
| d |
Tactile, with no writing system. The material has no text and is communicated only as graphic, i.e. a raised line diagram or drawing. |
| u |
Unspecified. The specific material designation is not specified. |
| z |
Other. None of the other defined codes is appropriate. |
|
| ǂd Class of braille writing |
The family of braille to which the item belongs. This is not the particular braille code, but the type of braille code used, representing different types of written symbols. Up to two braille types may be indicated, or the cataloging agency can choose to encode only the predominant type. Multiple codes are coded in order of predominance, if any. Also coded to identify the class of braille writing used for the text labels of cartographic or graphic items. If only one code is assigned, omit the unused second position. Note: Do not use subfield ǂd when a class of braille writing is not specified.

| ǂf Braille music format |
Three-character code that indicates the braille music format of the item. The music formats are the way measures, sections, parts, and related information, such as words, are presented in relation to each other. Up to three formats may be indicated, left justified in order of predominance. If fewer than three codes are assigned, omit unused positions. For example, the music format defines how the music for the right and left hand are sequenced and related to each other in braille. Multiple formats are sometimes employed in the same piece of music. For example, a vocal part and text are in one format and the accompaniment is in another. Note: Do not use subfield ǂf when a braille music format is not specified.
| a |
Bar over bar. Measures are displayed in units called parallels and that the beginning of each part’s measure is vertically aligned with the beginning of the same measure for the other part(s). This code is used chiefly for keyboard music. |
| b |

| f |
Section by section. Hand or part signs are prominent in the left margin. |
| g |
Line by line. Lines of text alternate with lines of music for the preceding text. |
