Missouri posting CW records online

I came across this interesting article through another blog I read (thanks Dick Eastman). As the 150th anniversary of the Civil War approaches archivists are working to post as many documents online as possible. Read a recent article about what Missouri is doing here.  The major site they are posting to is http://www.missouridigitalheritage.com/ . This looks like it could be a great site if you are researching anything to do with Missouri wheter related to the Civil War or not.
