Tons and tons of magic items for your 4e games. Broken up basically the same way they always have been. Armors, Weapons, Swords, Potions, Wands, Rods, Staves, and Miscellaneous. At 250+ pages with multiple items per page this is a packed book and there is something here for everyone.
Looking at this with an eye towards other editions, you could convert these to 3e without much difficulty. Other editions have more or less the same items (or similar ones) in edition specific books (The Book of Marvelous Magic comes to mind). But still a good selection for the money and a must have for the serious 4e player.
