A change to my blog

You may notice something new in this blog: along the right side, I now have Amazon links to books I've referenced in my postings. When I discuss or recommend a book, it's something I feel strongly about and I very much hope that others will read the book too. So the link is, in part, a way of encouraging people to get a book I believe contains valuable information or analysis. And -- here's the full disclosure -- I stand to make a few (a very few) cents here or there on any purchases you do make through the link.
