Many thanks to David French for allowing me to re-post his message here:
Today is a very exciting day. The 1940 Census is now available!
Getting Started Researching the 1940 Census
How to Access the 1940 Census in One Step by Stephen P. Morse, PhD &
Joel D. Weintraub, PhD
Other sites are also in the process uploading the census images.
It may take a little while for the images to load as many people are
on the 1940′s Census website, but should get faster as the day goes
Also, over 100,000 volunteers will begin working on producing the
index. You may also join this indexing project.
