I'm afraid this post is for us older guys (I'm 50), but anyway, long before the Internet I used to love any book or magazine I could get ahold of to document my beloved sci-fi shows.
FANTASTIC TELEVISION was and still is a great book, and loaded with hundreds of photos (a big deal before the Net came along):
This book even got into near-genre shows I loved like BEWITCHED, and gems from before my time like Julie Newmar (Yeah, Baby!) as a sexy fembot in MY LIVING DOLL.
