I work in a college library and I've done a search on the site libraries use to see if a book is located in a library anywhere in the WORLD. This is the site where you can search to see if your book is located in a library: http://www.worldcat.org/
I'm wondering if you'd like to have your book added to the collection at the college library where I work (New Jersey). If so, you can send me an email through curezone with your email address and I will write from my work address to tell you where to mail a copy of the book.
By having your book in a library, people who don't have the money to purchase it can have access to it. Many libraries share books throughout the world through the Interlibrary Loan System, so getting just one book into a library gives people access throughout the world.
