If you haven’t checked it out yet, take a look at the Digital Public Library of America at https://dp.la/ .

From their website:  The DPLA connects people to the riches held within America’s libraries, archives, museums, and other cultural heritage institutions. All of the materials found through DPLA—photographs, books, maps, news footage, oral histories, personal letters, museum objects, artwork, government documents, and so much more—are free and immediately available in digital format.

The DPLA is a nice resource for genealogists because you can search for information at a local level by going to https://dp.la/map .  There, a map shows 567,353 results with location coordinates from over 120 contributing institutions.  You can click on the map to get to the place which interests you.

You can also search by timeline which is fascinating – go to https://dp.la/timeline .  There is a slider that can move from year to year and will tell you how many items are available from that year from the DPLA collection.  Included you’ll find maps, books, oral histories, letters, and much more.

I did a quick search on my family name and found a photo of my father from when he was in school that I had never seen before.  Now I’m hooked and I would definitely recommend checking the website out.  Happy research!
