Websites like FamilySearch.org and Ancestry.com are not the only ones to offer digital content helpful in family history research. Many US states have their own digital collections of old newspapers, vital records, historic photos, military records, voter registrations, probate files, and more.
The Library of Congress published a comprehensive list of state digital archives last week in the article 71 Digital Portals to State History on their digital preservation blog, blogs.loc.gov/digitalpreservation (keep scrolling down until you see the title).
Whether your ancestors were from Alaska or Florida or somewhere in between, there may be records about their lives in a state digital archive. And you can search them for free, from home!
