Written Book

Written Books are created after a Book and Quill is signed. In the inventory, written books have a purple hue (similar to enchanted items) when obtained. The label does not say "Written Book", but what the player titles it, unless the item is spawned in through /give or with an inventory editor. It will say the title on the top line of the label, and "by username" on the bottom. Username is the username of the player who wrote the book, or "Player" if signed while playing offline. The icon of the written book is slightly different from the book and quill's icon, showing the same red book, but without the quill. The contents of a book are an extra set of data attached to the item. This means that when a book is destroyed, its contents are lost with it (unlike the case with maps).

When Written Books are obtained with /give or inventory editors, the label will only show "Written Book" and will be blank when opened. The book is signed and cannot be edited.

With the addition of the Ender Chest, it is now possible to send mail on multiplayer servers by titling the Written Book "To: Player1 From: Player2", where "Player1" is the name of the recipient and "Player2 is the players name.

History
Written Books were added in Snapshot 12w17a along with Book and Quills. They will probably be included in the next update.
