Reception.
Richard A. Edwards reviewed "The Astrogators Chartbook" in "The Space Gamer" No. 38. Edwards commented that "Considering the cost of photocopying all these maps out of a friend's copy, it is worth buying the book. The types of grids picked for inclusion are the most current in "Traveller" usage. It is a must for all "Traveller" referees."
