Another Change to the Sidebar

I decided to put a link to Amazon.com with the book that I am currently reading. I have not gone commercial as I am pretty sure that I will not make much money off of it, but if it interest you, then link and buy. Also through a banner ad at the bottom of the page. If I make a few cents a month, it will be worth the time and effort that I put in. I may even consider putting in a link or two to them in my posts if I think appropriate for the topic. Anyway, just letting my few readers that read regularly about the change.
