These library databases offer professionally produced streaming videos and TV shows (BBC, Ken Burns, National Geographic, etc.). A college username/password is required to access these from off campus.
If you're doing a presentation in class, perhaps create a short video clip using the video databases above. These databases will help you create a citation.
Below are links to a few interesting video, audio and photographic travel sites.
Search these for videos and images to add splash to your presentations! Make sure to cite them, of course.
