I've just ordered TATV Season 3 and Return to Tomorrow and look forward to reading both of them. I realize TATV has its many faults, but it still has plenty of value; a great many behind the scenes notes and memos, as well as interviews and step by step story evolution, that I never would have seen otherwise. I also don't mind editorializing by the authors. I actually enjoy reading opinions to go along with it, just to know his or her take on it. Until someone else puts the info out there, this is what we've got.
Other behind the scenes books provide information from research done from memos and archives without reprinting or summarizing the correspondence verbatim. Many just recount what as said by summary.
The Time Tunnel: A History of the Television Program by Martin Grams, Jr. and
The 12 O'Clock High Logbook: The Unofficial History of the Novel, Motion Picture, and TV Series by Allan T. Duffin and Paul Matheis both do this, but neither series has nearly the following of
Star Trek. So they don't have to bear the same intense scrutiny. At some point, you have to trust the authors have done their work and are relaying this information accurately. Sadly, Cushman didn't do this in some key areas and has a problem admitting when he's wrong, so that throws his entire work into question for some people (hell, if I could spot some errors, anyone could). I tend to enjoy his "take" on some things as anecdotal and am willing to go along with his summarizing as correct. I also now accept his understanding of ratings are flawed, but I'm more interested in the crafting of the stories and what the production staff was dealing with. And learning more about the other people involved aside from the usual suspects. I'm particularly interested in the third season, since so comparatively little has been written about it.
Having said all that, I still read Harvey's blog with great interest and trust his research. Between Cushman's work and Harvey's (and Harvey's corrections

) a pretty good picture emerges. Like others, if someone else - or Harvey himself - wants to put out a really correct accounting in print, I will happily buy it. Seriously, count me in.
Return to Tomorrow holds great interest for me and I'm really looking forward to devouring that as well.
Now if someone would just write really good behind the scenes book on
Voyage to the Bottom of the Sea, I'd be in heaven.
