From publisher blurb: 10+ Treasure Vault is a compilation of all of our previous 10+ Treasures volumes, with some additional magic items drawn from our extensive and excellent library of Dungeon World classes, giving it a total of 147 magic items. Its purpose (aside from giving you a bunch of magic items and magic item-creating tips) is to provide a more convenient print option: instead of ordering all of the individual 10+ Treasures volumes, you can instead get everything in one, substantially larger book (and PDF).
