[Classweb-users] Subject heading query: Talking books vs. Audiobooks?

[Benedetti, Susannah]

Greetings,

I have a question regarding the difference between the following subject headings:

650#0 Talking books.
and 
650#0 Audiobooks.

My question is whether both headings are appropriate for use with commercially produced books on tape/books on CD sold to the general public.

The heading Audiobooks is used for Books on tape, Recorded books, etc., while the scope note for Talking books reads:"Here are entered works on spoken texts recorded specifically for use by the blind or people with visual disabilities."
I am unfamiliar with spoken texts recorded specifically for the blind or people with visual disabilities, but the implication is that they are different than commercially produced books on tape/books on CD. Is this the case, and if so, are the two headings mutually exclusive?
Any assistance or guidance is greatly appreciated.

Best regards,
