I have been playing D&D for most of my life and i have never found a book that i like as much as this one. i carry it with me to every game. this book collects spells from almost every source possible (dragon magazine, the wizards of the coast website, and past books) and puts them all in one place without the bull. i don;t feel like wizards of the coast is trying to scam me for any money like i do when i purchase some of their other books, this is a serious tool to DMs, Wizards, Sorcerors, Rangers, Clerics, Paladins, Bards.... pretty much everyone except fighters and barabarians will find this book useful at one point or another.
