Books are now fairly hard to make, but with this it would take a lot less work, but a bit more time to make. What you would have to do would be to get a block of clay, and a stick. If you know, Sumerians long ago created the first way to write, they used clay and a stylus(stick) to draw and then let it dry. What could be made, is when you craft a block of clay and a stick, it would be called a tablet and stylus. It would work as a book, right click and type, it would just be one page and no title, but it is better than not writing at all. These cannot stack and would benefit mostly in multiplayer servers and adventure maps. The other catch(unless you are in creative): it takes 10 minutes for the clay to dry into a "stone" tablet. This would be an easy craft, and a great way to use mail without getting leather (if you love cows) and sugarcane if your house is nowhere near water or something. I believe that other people wouldn't think of this because they are getting creative, how this is a simple but could change mine craft. Who wouldn't want a way to make books other than a book and quill? I do not believe this has already been a mod, and I doubt it too. This is my idea and contest entry, enjoy the magnificence. :)
