Scrolls

Scrolls return in Diablo III, with some key differences.

Diablo II had just two types of scrolls; Identify and Town Portal. Both types could be stored in tomes or books, that held up to 20 of them, for convenience. (It's not known if there are tomes in Diablo III; possibly not, since scrolls stack.)

Diablo III also has just two types of scrolls (so far revealed).

Identify Scrolls, which work just as they have in the other games in the series. All types of magical items, including sets, uniques, rares, legendary, and others, are found unidentified. An NPC can identify them for you in town (Deckard Cain in D2, and probably in D3 as well), or they can be identified anywhere by the use of an identify scroll.

Scroll of Wealth is a new type of scroll in Diablo III. Using this scroll allows you to sell items anywhere, even out in the dungeons. It's essentially a convenience.

Town Portal Scrolls are out of the game entirely. The D3 Team felt they were exploitative and made immersive combat too hard to create. So they're gone; their removal doing much to spur the creation of scrolls of wealth, as well as the salvaging system.
