The Formats search filter includes Braille and Books (large print) as options.

When Braille is selected as a filter, records applicable to the search term used will be returned if the Leader position 06 = a and the 008 position 23 = f.
When Books (large print) is selected as a filter, records applicable to the search term used will be returned if the Leader position 06 = a, Leader position 07 = a, c, d, or m, and the 008 position 23 = d.
The Accessibility Features search filter shown here is not available until October 5 2026.
The Accessibility Features search filter will enable patrons to search for items with desired accessibility features.

When a search filter option is chosen, records applicable to the search term used will be returned if a 341 field in the MARC record contains the corresponding value. A record with the 341 fields pictured here would be returned as a result if the Textual, Auditory, Closed captions, and/or Audio description filter options were chosen.

This table shows the filter options and their corresponding values in the 341 field. These values are from the controlled vocabulary Schema.org Accessibility Properties for Discoverability Vocabulary and so the 341 field must include a $2sapdv to indicate this vocabulary is being used.
