For dancers as well as educators, you will love the interactive site that Jacob's Pillow recently launched. Jacob's Pillow is the longest running international dance festival in the United States, and they have hundreds of videos from their archives now online. What a gift.
Yesterday I watched a Ted Shawn video from the 1930s. The videos date back from the 30s and run the whole way through to the present. You can search the site by artist names, genre, or era.
This will become a great and valuable resource to use within college courses.
