"We have what we call Canon, which is the screenplays, novelizations, and other works that are directly tied into continuity, and then there are a lot of marginal things, like the old Marvel Comics series, that we don't really try to work into the continuity when we're planning new projects. Even the LucasArts interactive games have a premise, a backstory with player characters that we're trying to tie into the overall continuity. It is sort of a godlike undertaking. We are creating this universe as we go along, but somebody has to keep his finger on everything that came before."
—Lucasfilm's then-continuity editor Allan Kausch, The Secrets of Star Wars: Shadows of the Empire
"Gospel, or canon as we refer to it, includes the screenplays, the films, the radio dramas and the novelizations. These works spin out of George Lucas' original stories, the rest are written by other writers. However, between us, we've read everything, and much of it is taken into account in the overall continuity. The entire catalog of published works comprises a vast history—with many off-shoots, variations and tangents—like any other well-developed mythology."
"After Star Wars was released, it became apparent that my story—however many films it took to tell—was only one of thousands that could be told about the characters who inhabit its galaxy. But these were not stories I was destined to tell. Instead they would spring from the imagination of other writers, inspired by the glimpse of a galaxy that Star Wars provided. Today it is an amazing, if unexpected, legacy of Star Wars that so many gifted writers are contributing new stories to the Saga."-George Lucus
"The Holocron is divided into five levels (in order of precedence): G-canon, T-canon, C-canon, S-canon, and N-canon.
G-canon is absolute canon; the movies (their most recent release), the scripts, the novelizations of the movies, the radio plays, and any statements by George Lucas himself. G-canon overrides the lower levels of canon when there is a contradiction. Within G-canon, many fans follow an unofficial progression of canonicity where the movies are the highest canon, followed by the scripts, the novelizations, and then the radio plays.
T-canon refers to the canon level comprising only the two television shows: Star Wars: The Clone Wars and the Star Wars live-action TV series. Its precedence over C-Level canon was confirmed by Chee.
C-canon is primarily composed of elements from the Expanded Universe including books, comics, and games bearing the label of Star Wars. Games and RPG sourcebooks are a special case; the stories and general background information are themselves fully C-canon, but the other elements such as character/item statistics and gameplay are, with few exceptions, N-canon.
S-canon is secondary canon; the story itself is considered non-continuity, but the non-contradicting elements are still a canon part of the Star Wars universe. This includes things like the online roleplaying game Star Wars: Galaxies and certain elements of a few N-canon stories.
N-canon is non-canon. "What-if" stories (such as stories published under the Star Wars: Infinities label), crossover appearances (such as the Star Wars character appearances in Soulcalibur IV), game statistics, and anything else directly contradicted by higher canon ends up here. N-canon is the only level that is not considered official canon by Lucasfilm. A significant amount of material that was previously C-canon was rendered N-canon by the release of Episodes I–III."
To sum it up, what is and what isn't canon is based on interpretation, and isn't distinctly clear cut. It's mutable, as long as it doesn't mess with George Lucus' films, he could give a rats ass.He personally doesn't pay attention to the expanded universe, and leaves those details up to LucasFilms and LucasArts. So yes the Jedi Path is Canon under the pretense that it is a licensed LucusFilms property. That's only because George Lucus himself admits he only told one story of the thousands upon thousands possible in the Star Wars universe. and for those other tales he leaves it up to the gifted writers around the world. I hope that answers your question.
