Larry Sanger, who helped create Wikipedia, launched a new site in October that makes available educational videos for students aged 3-18. These videos have been available for public viewing from different sources. What Sanger accomplishes with www.watchknow.org is a single site for free to view educational videos that are organized by topic for easy searching. Categories include math, literature, languages and of course, history. I just took a peek at The Ancient Civilizations of Mesopotamia - An Introduction produced by National Geographic, Genghis Khan Biography by BBC and The Vikings by The History Channel. Be sure to make note of this great resource.
