Here is a website to let you know about. I think it is pretty fantastic.
It is all about Missouri Heritage. It has lots of information including photographs, exhibits, educational pieces, history lessons, vital records information and images, and much more.
It has images of records such as death certificates, birth records, judicial records, searchable naturalization database, and probate records.
There is information about Lewis and Clark, the Missouri Mormon War, the Dred Scott case, and Jesse James.
There is so much here. If you like history, whether Missouri history or not, you'll like this site.
