If you all are like me, I am very specific with how I organize the numerous books I have saved over the years. I want to know where a specific book is that I am searching for and not have to go dig around in order to find it. I have attached a link to an article that gives people like you and me useful tips on how to organize our libraries. I hope these suggestions will lead you to your perfectly ordered book shelf!
