Recently we received a new errata and addenda to the Nemeth lesson manual, AN INTRODUCTION TO BRAILLE MATHEMATICS. Is this considered an update to the Nemeth rules and as such do we need to make note of this update on the transcriber's notes page? For example:
Portions of this text are transcribed according to the rules of the Nemeth Braille Code for Mathematics and Science Notation, 1972 Revision, 2013 update.
A transcription is brailled based on the BANA braille codes, not on the lesson manuals. (The lesson manuals are not BANA publications.) The BANA Updates apply to the Codebooks. The most recent Nemeth code update was posted on the BANA website in 2012.
