Selsor was introduced in Rules of Engagement: The Rebel SpecForce Handbook, a 1997 West End Games sourcebook authored by Timothy S. O'Brien for use with Star Wars: The Roleplaying Game. The 2009 reference book The Essential Atlas placed the Selsor system, and therefore the celestial body Selsor, in grid square O-14.
