Ancestry.com announced Free Access to immigration and travel records from around the world through September 5th.
This is a very large collection of materials. If you are not an Ancestry subscriber, this would be a perfect time to drop in to take a look and do some serious research in their travel and immigration records.
Another note, Ancestry has announced that the 1940 census will be available for free, once they post it after April 1, 2012. I’m looking forward to it. (But to be clear, the 1940 census will also be available on the National Archives website for free. It will be up to Ancestry to demonstrate compelling value in terms of usability and searchability to make the 1940 census a differentiator for Ancestry.)
