Outside of Wikipedia, where might one go to learn more about the Reformation? While one can always look up information in an encyclopedia or another book, there are some reliable websites online that I would recommend in order to learn more about the Reformation and Northern Europe. The site, Europe in the Age of the Reformation, is a course site for Dr. Knox of Boise State. He has compiled numerous resources and essays in this tutorial and accompanying site.
