It will be free at Ancestry.com for a year. There is no index anywhere yet. To find people, one must know where they were living. As of now, Ancestry has some or all of DC & NV online. The National Archives will release it on their site at 9am ET. Nat Archives has maps of the Enumeration Districts (which are needed to find people) or one can use this handy calculator: http://stevemorse.org/census/unified.html
I consider this a very exciting day. It will be the 1st census with one of my parents in it - my deceased father...
Thank you!
Ping for later.
