As far as Star Wars books, I've probably read approx. 50 of them give or take a couple.
I started with the Thrawn Trilogy, then read the novels based on the original movies, and then went on from there... NJO, Legacy of the Force, Fate of the Jedi, individual books like Outbound Flight, I, Jedi, Darth Bane's Trilogy and many others in between. Maybe that would be more than 50! Lol
I've also read some of the graphic novels such as the Legacy series.
