It was announced today that digitized images of Michigan death certificates from 1921 to 1939 are now freely available online. Digitized certificates for the years 1897 to 1920 were previously available. The index to 1940 through 1952 is said to be available soon. Privacy restrictions keep the actual images for that time period from being released. However, release will come annually, as the 75-year restriction passes. The addition of the 1921-1920 death certificates now brings the total number to 2.6 million.
