Somehow I missed it but Star Trek: The Original Series: Assignment: Eternity
numbered novel #84 was finally released as an ebook back in April 2013. I know a few of us have discussed older TrekLit titles that are AWOL for various assumed reasons that we would all like to see make the leap to digital. This was one of mine. I'll need to go through the list of missing titles soon to see if any others were slipped in and I missed them too.
This one was released on Amazon and Barnes & Noble, and I'm assuming other resellers as well, on April 23, 2013.
Is anyone aware, off the top of their heads, of any other older Pocket/S&S titles that weren't available as ebooks?
