C-SPAN may not be the most riveting television, but it does provide a way of experiencing American politics without some O'Reilly or Olbermann telling you what to think. It's the primary source, unmediated. So it's great news that the network is making its entire archive-160,000 hours of video, dating back to 1987-available online in a searchable, user-friendly C-SPAN Video Library.You can hear the vice president of C-SPAN describe the project in this 10-minute video. The world just got a little better informed (and Jon Stewart's research team just struck gold).
