GURPS Space Atlas 4

GURPS Space Atlas 4 is a science fiction supplement written by David Pulver and Stephen Dedman published by Steve Jackson Games in 1991 for "GURPS Space".
Publication history.
As its name suggests, "GURPS Space Atlas 4" is the fourth "encyclopedia" of planets and planetary systems for use in "GURPS Space" campaigns, this one written by David Pulver and Stephen Dedman, with illustrations by David Midgette, and cover art by Alan Gutierrez. 
In the 2014 book "Designers & Dragons: The '80s", game historian Shannon Appelcline noted that the ""GURPS Space Atlases" (1988–1991), "GURPS Space Bestiary" (1990) and "GURPS Aliens" (1990) helped fill out the "GURPS Space" world."
Reception.
In the February 1993 edition of "Dragon" (Issue #190), Rick Swan called the book "an invaluable reference not only for "GURPS Space" enthusiasts, but for science fiction gamers of all persuasions." Swan concluded by giving the book an excellent rating of 4.5 stars out of 5, saying, "the quality of writing, effective graphics, and diversity of the entries distinguishes "Space Atlas 4" from its run-of-the-mill competition."
