This is related to my previous post. I happened upon a site of picture books in PowerPoint format. Most range in price from $1-2. I'm not really sure how this is legal, but there are some good books on the site.
Update: I just received email from the company that offers these powerpoints. They have permission to create/sell a certain number of powerpoints for each title. That's why some books are listed as unavailable. They have to request permission to make more copies. I'm relieved to hear that they are going through the proper channels to do this.
