The library nerd in me loves that this video even exists. Matthew Battles is an author and librarian. His book, "Library: An Unquiet History" talks about how libraries constantly are re-invented for the needs of the time.
In this video, Battles talks about the 19th century Chartist movement paved the path toward the public library system we have today. Toward the end of the video Battles makes the point about how the camp libraries of the Occupy movement will also shape how we share information in the days to come.
