Independent book stores are at risk of going out of business. Look around and see what's happening. I have always loved bookstores that are individually owned. But, they are a dying breed. Amazon, Borders, Barnes and Nobles are all great resources, but do you want the market to be dominated by just a few big businesses? I sure don't!
You can help by buying books from your favorite independent bookseller. Don't use the book store as a library! Get some food there, if you can. Many bookstores use a little restaurant as a suppliment to the atmosphere of the store and a valuable revenue stream.
