Many genealogists are awaiting April 2, 2012 with baited breath. Why? Because that day, the 1940 census pages will be available publicly. Unfortunately, unless you happen to know exactly where your family lived, you will have some work ahead of you! It's being released without an index.
That's a solvable problem. Archives.com, FamilySearch.org and several other groups have joined together to create the 1940 Census Indexing Project. The idea is pretty simple. Using indexing software, volunteers will read the original images, fill in the necessary documents, and create an index we all can use. And you have the opportunity to help. Visit http://the1940census.com. The website offers plenty of details about the project. I'm looking forward to participating.
