I have a veritable shelf full of these books, published by Wizard Books. 25th anniversary edition of Warlock of Firetop Mountain, Talisman of Death, Spellbreaker, Howl of the Werewolf (which adds a few more mechanics to the base game stats), Stormslayer, and I recently purchased the entire Sorcery! series on eBay. I once had a book confiscated by a teacher for reading in class, heh. It's good to see these books are still going strong, nearly four decades after they were first published.
