Srofezilla, good point!
How are you considering three times. Are you counting "Dark Empire," "Jawas of Doom," "Tales of the Bounty Hunters," "Tales from Jabba's Palace," and "The Mandalorian Armor?"
There's a good breakdown at http://scifi.stackexchange.com/questions/50775/which-book-explains-the-story-about-how-boba-fett-escapes-his-fate of four of those five.
Also, be sure to check out the Fettpedia record, now updated for the Sarlacc:
