I can't say that I have only one canon. It really depends on my mood. Let me just list how I look at it, depending on what I'm feeling at the time.
-The OT
OR
-The PT (movies and novels together)
-The OT (sometimes including the novels, but not usually)
OR
-The PT (movies and novels together)
-Clone Wars CGI and traditional animated, favoring CGI.
-The OT
OR
-The OT
-The Thrawn trilogy
-And sometimes I'll include the Jedi Academy Trilogy
-And sometimes I'll even let in Shadows of the Empire
OR
-ANH
-Splinter of the Mind's Eye
OR
-The OT
-OT novelizations
-OT radio dramas
-OT deleted scenes
-The Star Wars Holiday Special.........Juuuuuuuust kidding!
I used to include everything that came out, even if I was not a fan of specific ideas, but as time went on, more and more crap became associated with the EU and I started disregarding most of it. As I've mentioned elsewhere, I cannot stand Dark Empire and don't like how big an influence it's had on the rest of the EU. The only thing I like that came from it was the Eclipse, but in the context of the rest of the timeline, I don't even believe such a thing could have been built. Since I stopped paying attention to most EU, I've never bothered to pick up a novel set during the PT timeframe (other than the PT novels themselves, of course).
