The Internet Archive is a an Internet Library of free videos, text, audios and other digital data. As they put it themselves:
The Internet Archive is a 501(c)(3) non-profit that was founded to build an Internet library, with the purpose of offering permanent access for researchers, historians, and scholars to historical collections that exist in digital format.
And now hopefully the video portion of it will (with your help!) be available with subtitles, further broadening the usefulness of the Internet Archive-provided data to users from all over the world.
