The Most Expensive Books
Books are generally pretty cheap for the value they provide, if chosen wisely. Just think of all the work that has been put into writing it, then producing and marketing it. You can find all the wisdom of the world for just a few bucks.
That's why I wanted to share with you this website I found, listing 10 of the most expensive books in the world. Check it out at http://flavorwire.com/251055/the-10-most-expensive-books-in-the-world. (No, I am not an affiliate for these auction houses.) Enjoy!
