Articles electronically for sale

Did you try to go to amazon.com, search for "books" and type in "blog" recently? Well, try it, it's interesting and quite illuminating. While I won't call 5-6 $ for an article "micropayment", if the option is to not get the article you so desperately need to quote, the price is not unreasonable. And getting it through Amazon puts it all under one established transaction agent. "One agent rule them all..." Let's hope the idea of micropayment grows a little more towards micro as the service is more commonly used.
