People in bookstores like to browse books, pull out a selected title, and read a few pages. If they like what they read, they will buy the book. Unfortunately, they are limited to the books on the shelves, which might not be what people want. For example, I wanted to look at books on building tree houses. None were available on the shelves. (I was referred to the local hardware store!) I wanted to flip through the 2009 Writer Watchdog. I couldn’t do it. I wanted to read a few pages of Blonde by Joyce Carol Oates. Not available. Maybe I could look at Interpreter of Maladies, the first book by Jhumpa Lahiri. Same problem.
