The card catalogue is the highlight of the mod, which documents where certain book sections are. There are twelve slots that have four entry areas in them. First is the description entry. This describes the book/set of books. Second is the section entry, or Sec. This is which part of the library/place the book is, since a library usually has multiple parts dividing different types of books. Third and fourth are the Row and Column (Col.) entries. These map the bookcase as a grid. You can place a row and a column, or a set of rows and columns. This allows for a complete documentation of a library.
Lastly is that you can make paper with other things than papyrus. You can make it out of string or you can make it out of wood pulp (wood pulp is a cooked stick). This makes books and shelves much cheaper.

The blue book is the crafting guide book, not included in this mod.
The cyan, red, and purple are all based off of textures made by jp. The others are from assorted texture packs and edited by me.
