The Library of Congress has recently posted a collection of Vaudeville-era (c.1897-1920) silent films on YouTube:
The motion pictures in the Variety Stage collection include animal acts, burlesque, dance, comic sketches, dramatic excerpts, dramatic sketches, physical culture acts, and tableaus. The films represented date from copyrights of 1897 to 1920; the majority are drawn from the Library’s extensive Paper Print Collection. The remaining films were produced by Hans A. Spanuth in Chicago from 1919 to 1920 for the series “Spanuth’s Original Vod-A-Vil Movies.” These motion pictures present a rare animated record of vaudeville acts from the turn of the century. Although not actually filmed on a theatrical stage, they sought to recreate the atmosphere of a theater performance by showing the types of vaudeville acts and performers that were popular at the time.
