Explanation
Code 51 is used to indicate that the publication can be read entirely by pre-recorded audio.
For a format like EPUB 3, this means that media overlay playback provides access to the full content of the publication.
Code 51 is equivalent to stating that a publication has a sufficient access mode of auditory.
Only for use in ONIX 3.0 or later.
