I'm glad you brought this up.
BANA has published two documents providing rules for using Nemeth Code and UEB together. The first was "Provisional Guidance for Transcription Using the Nemeth Code within UEB Contexts" (approved November 2014). The second, and current, is "Guidance for Transcription Using the Nemeth Code within UEB Context" (approved June 2016). This replaces the first publication and is now the only document dealing with using Nemeth Code within UEB that is available from BANA's website. It provides expanded and more honed rules than did the Provisional Guidance.
This Ask an Expert thread was started when only the more brief Provisional Guidance was available, before the release of the current Guidance.
