Instead of going to the mall for the Presidents Day sale, you can really celebrate by brushing up on some presidential history. A great place to start is the Internet Public Library's POTUS which provides biographical information, historical documents, and audio and video files. If this doesn't satisfy your historical sweet tooth, check out Public Papers of the Presidents at the American Presidency Project which has digitized over 85,000 documents related to the Presidency, including audio and video. Still not enough? The Atlas of U.S. Presidential Elections contains detailed national results of all U.S. presidential elections since 1789.

...or maybe a little bit longer than that. On November 19, 1863, President Abraham Lincoln delivered the Gettysburg Address. In this short, but powerful speech that is still known almost one hundred and fifty years later, Lincoln spoke about ideas of both war and freedom.

White House Pets takes a look at the more than 400 pets that have lived there over the course of 200 years. Produced by Animal Planet,  the DVD is  a fascinating look at the bears, parrots, dogs, and cats that have roamed the halls of one of the most famous homes in history.
