The Interim Manual for Foreign Language Braille Transcription is the only published set of guidelines for foreign language braille. It is available ONLY from National Braille Association, so please contact the NBA national office. This publication has the general procedures for transcribing in foreign languages and has the specific special symbols used for accented letters in several foreign languages, including Spanish. It is important to be aware of both the formatting requirements AND the usage of braille accented letters.
A new, updated BANA foreign language braille document is currently being edited, but has not been released for use by BANA yet.
