Sadly, by that time, S&S had given up on Trek audio, and nobody's really tried to start it back up again.
Didn't Margaret Clark recently say in an interview that S&S Audioworks was looking into resurrecting the line?
My page of annotated Trek audios:
If a blind person purchases a book, do they have 'right' to have it read to them?
It's my understanding that some groups of vision-impaired people do this regularly with all kinds of books. MP3 files etc must have made sharing so much easier. I think there is some kind of copyright waiver they organise, but the resulting products cannot be shared beyond the group, of course.
Nearly all of the audiobooks that are available are heavily abridged too, it's a very sad state of affairs.
Once upon a time, abridgments were preferred over full-length. Mainly because of the huge boxes required for commercial unabridged-books-on-cassette.
