1997: BABYLON FIVE SECURITY MANUAL (BOXTREE/ CHANNEL FOUR BOOKS)

From 1997: the British edition of the BABYLON FIVE SECURITY MANUAL, published by Boxtree Books.

As the title and blurb suggests, this was an in-world guide to security on the eponymous and much troubled space station. 

As with all such books, the extent of the appeal depends entirely on your willingness to suspend disbelief and immerse yourself in the imaginary. For the most part, I'm much more interested in the behind-the-scenes factual stuff (B5 was, thankfully, blessed with a number of fine accounts of the making of the show) rather than this type of book. But, nevertheless, it's good fun and well illustrated.
