Now, this is neat: The UK Sci-Fi TV Book Guide
Just had an email from the proprietor of the above website asking if he could add the Complete Starfleet Library site to his links page, and answered yes, of course. And checked out his website. It's a hell of a thing. Lists of tie-in books for dozens of TV series, UK and USA. Blake's 7, Red Dwarf, The Prisoner, Space: 1999, pretty much everything but Doctor Who, and he's working on that now. If you were curious whether there were Quatermass books, you have a place to go now. (I have one. Now I know there are others.) Looks like the focus is more on script books, novelizations, and novels than on nonfiction books, but I could browse through there for quite a while. Good grief, there's a Star Maidens book!
