There are many publically available collections of video and audio files. Of course, one must consider copyright laws when downloading anything from the web. Here are some sites that offer downloadable video and sound files.
Imageworks is located on the second floor of the Art, Architecture & Engineering Library. Slides and videos circulate to UM affiliates with a valid ID. Slide duplication services are available, as are video and slide viewing stations.
In addition, the University of Michigan has access to a wide range of digital image databases. For more information on these databases and on the collection of visual resources, please see the Images Guide.
