I've had this softcover on my keeper shelves for ages, and I think it's time it went traveling. It's a guide to the original Twilight Zone
TV series, with plot descriptions, cast and crew information, and behind-the-scenes discussions of each episode. Lots of good information here! I've seen the series many times and still tune in to TZ marathons to watch my favorites again - and browsing this book reminded me of the ones I still look forward to watching...
[There's a TV Tropes page
on the series with some entertaining tidbits.]
