Take a look at the 4/4/12 Eastman Newsletter article (right hand column on our website) on the access to the 1940 census for the first 2 days. Looks like we are really interested in our parents and ourselves.
The first day there were 22.5 millions hits in the first three hours; 100,000+ every 10 minutes. What’s more amazing the second day there were 40.1 million hits in the three hour peak time. Take a look at the numbers; they are amazing. Then you might consider becoming an Indexing volunteers to make this all more available.
