The historical slideshow below is a standard mp4 format, but requires either quicktime player or windows media player to view it. These viewers are usually pre-installed, but might need to be updated. Although we have compressed this video slideshow considerably, it is still nearly 30Mb in size, is about 20 minutes long and will take awhile to begin playing (depending on your internet connection speed). There is background audio, so you might want to turn up your speakers.
