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.
Keep watching. Some of them have Nimoy's version right after Shatner's.
