Bookstand

The Bookstand is a block from Mystcraft that is used to hold Linking Books and Descriptive Books. While a book is on the stand it is immune to any damage from the world. This can help prevent loss of your age or your way home.

Usage
Place it in the world, and right click it while holding your Linking Book or Descriptive Book. To remove the book from the stand you can either crouch+right click it with an empty hand, or you can right click it and take it out of the GUI.
