Just when I thought that Wikipedia couldn’t get any more useful than it already is, they added a really cool new feature: Books. Put more accurately, the ability to take Wikipedia content and create your own books that you can either download as a PDF, or have bound into a real book. As a test run, I created a single article book based on my latest interest, Electronics. I’m am very impressed with the quality and formatting of the book. I’ll have to spend a little more time looking at the more advanced features, but I can see myself using this feature quite a bit.
