Wasn't the SOTE source book a part of the old West End Games Star Wars RPG? I think I might still have that in a box. IIRC, it was basically a bunch of stats for the characters/spaceships/new aliens that appeared in the book.
Actually, a lot of the sourcebooks are really good reads as well as having rpg stats, etc. I only wish I could find some in book form(I can only find PDFs now).
