What is it: CriticalPast.com was a stie created by a team of professionals in the archival research field. The site contains over 57,000 videos and 7 million still images from the past that are arranged nicely by date and location. I will note that the images and video are available for purchase but can be viewed from a searching aspect. I do like that you can search by decade through a visual time line at the bottom of the home page.
How to integrate it into the classroom: Bring you historical figures to life by showing students short clips of those figures at various events. Listen to John F. Kennedy's Inaugural Address or The Apollo 11 Moon Landing. One downside is that the videos can not be played in full screen mode. But there are some work arounds.
