Good work, my friend. I would interested in acquiring those transcripts, since some of them aren't opening on the site you posted. I should add that someone on YouTube has been posting versions of the Sci-Fi Channel Special Edition segments of Leonard Nimoy from the third season. Here is the link: https://www.youtube.com/user/billotto51?feature=watch
Actually, those are the Shatner versions of season 3.
But as for the Nimoy scripts, ask and ye shall receive.
