The "Monster Encyclopedia" is a guidebook featuring over 1600 types of monsters. It details everything from familiar monsters like Slimes and Hargon to lesser-known ones. I bought this book and only flipped through it briefly before storing it away in the back of the bookshelf. It's in excellent condition, with no creases and the obi (paper band) still attached. "The History of Adventure" was another book released around the same time, and it was a huge hit. It provides detailed explanations of the Dragon Quest series, from the Dragon Quest (Famicom version) to Dragon Quest IX (DS version). This book is also in storage, in the same condition as the Monster Encyclopedia, with no creases and the obi still attached.
