The X-wing: Rogue Squadron Sourcebook was a proposed West End Games sourcebook that would cover the characters, events, and backstory of the X-wing novels. The majority was to be written by Eric Trautmann; there would also be a short story by Michael Stackpole detailing Corran Horn's experiences at the Battle of Bilbringi. It was to be 144 pages and cost $25.^[source?]

After WEG went bankrupt, the only remaining copy of the sourcebook was held on a CD, which was later discovered to have been corrupted.^[source?]
