Today at about noon we passed 1,000,000 books read on Tar Heel Reader. I've embedded a video below showing how its use has spread over the 22 months since we began back in May 2008. If you have sound you should be able to hear a varying pitch indicating how many books were read each day. Listen for the pitch to go down during the summer and at Christmas.
We've got books in 12 languages on the site and they have been read in 133 countries. Our server has been accessed over 70.8 million times and has pushed about 1.1 terabytes of data onto the web.
