Publication history.
In the 2014 book "Designers & Dragons: The '80s", game historian Shannon Appelcline noted that Steve Jackson Games decided in the early 1990s to stop publishing adventures, replacing them instead with genre sourcebooks. As Appelcline commented, "SJG was now putting out standalone "GURPS" books rather than the more complex tiered book lines. This included more historical subgenre books. Some, such as "GURPS Camelot" (1991) and "GURPS China" (1991), were clearly sub-subgenres, while others like "GURPS Old West" (1991) and "GURPS Middle Ages I" (1992) covered genres notably missing before this point."
One of these "sub-genre" books was "GURPS Vikings", a 126-page softcover book designed by Graeme Davis, and edited by Steve Jackson, with interior art by Topper Helmers, Don Arburn, Carl Anderson, Denis Loubet, and Doug Shuler, and cover art by John Zeleznik. It was published by Steve Jackson Games in 1991. 
In 2002, Steve Jackson Games published a second edition of this book to be played with rules of the third edition of "GURPS". The 128-page softcover book was again designed by Graeme Davis, with illustrations by Paul Daly, Shane L. Johnson, Garry McKee, Klaus Schwerinski, Carl Anderson, Topper Helmers, David McKay, and Michael S. Wilson, cartography by Mike Naylor, and cover art by Alex Fernandez. 
Reception.
In the May 1992 edition of "Dragon" (Issue #181), Rick Swan thought that this book "offers something for Vikings of every persuasion." With regard to the history chapter, Swan was impressed by the author's ability to "pack an enormous amount of information into a relatively few pages, emphasizing many intriguing facets of culture and economics." However, he found the chapter on new character classes "isn't particularly inspiring," and he also noted that "magic is underplayed... a disappointing section." He did like the new monsters, "a good mix of the ordinary and the unusual." In conclusion, Swan gave the book 3 stars out of 5, saying, "This is the thinking person’s guide to Vikings. Novices may be overwhelmed by the amount of detail, and the shallow treatment of fantasy may discourage players who are less interested in mastering the Norse legal system than in hacking up sea monsters. But for mounting a strict historical campaign, "GURPS Vikings" is the book of choice.
