You can make a book in normal minecraft...
book then feather then ink sack
To write in a book, you don't need a pen. You just start typing. There is no pen in vanilla Minecraft.
If you have the recipe book mod installed, you craft it with 1 ink sac and 1 book.

In Minecraft 1.3.1, they added the book & quill item that lets you write and edit a book in Minecraft vanilla. If you combine a book (gotten from 3 papers and a leather) with a feather (dropped by chickens when killed) and an ink sac (dropped from squid when killed), you will get a book & quill that you can write in. You're welcome for the info!
You place a box of 8 wooden planks with redstone dust in the middle.
The crafting recipe for books in minecraft was first changed in version 1.3.1. It is now crafted with 3 Paper; 1 Leather.
You can't but you prolly will able to in future.
You should be able to craft a arrow and in the next update you will also be able to make a book and quill.
