Whenever I think of an author, or one of their 'hard-to-find' books I go to the Book Oasis. Chances are they have it. My kids are voracious readers. I always see their favorite authors on the Oasis shelves.
I keep hearing about Kindle this & Kindle that. Kindles will never replace the sweet smell of a well read book. Try navigating a few chapters back when you need to reference something, or look at a map in the front of a book, ie; The Lord of the Rings trilogy.
