Published by Boxtree in the UK and Del Rey in the USA.
Dining on Babylon 5 is a rare gem, featuring a choice of alien recipes collected by the Head Chef and proprietor of the Fresh Air restaurant, Emerson Briggs-Wallace (with some help from Stephen Smith). Enjoy zoonburger, yogtree and, of course, that famous delicacy Spoo (menus also suggest human substitute foods). Published by Boxtree in the UK and Del Rey in the USA.
The book Creating Babylon 5 by David Bassom was published earlier by Boxtree in the UK and later by Del Rey in the USA. It details some of the show's ground-breaking production techniques and CGI effects, describing the origins and production history of the show, with background material, character bios, and some episodic synopses.
