All of my personal canon centers around, or is connected to, these stories. I put the published NPR script in there because it has some scenes that were trimmed (for time) in the broadcasts. The 1977 version of Star wars, while not something I watch terribly often, is still the standard bearer of my canon.
My personal canon will be no doubt grow as I read some more of the Zahn novels. Truthfully, I can hardly put the Thrawn Trilogy down. Fantastic stories and very adult.
An aside; This board is responsible for that list, by the way. I was first-film-only 8 years ago and had been for many years before that. The importance this board has played in re-engaging me as a fan and making the Star Wars universe deep and mysterious again can't be over-stated.
