Actually the canon of Star Wars was a bit complicated. There were different tiers of canon. Movie canon, book canon, and everything else (I think). Basically everything was canon unless it was directly contradicted by something in a higher tier. It's actually why I ended up reading over 100 Star Wars books. They all were connected and built off each other, and a few things even ended up in the prequel movies and special editions. (The name Coruscant, Aayla Secura, Dash's ship in A New Hope). Now the books are just one shot nothing stories with no consequences or point.
And yes, I'm aware that most people don't care at all.
