Online Historical Maps: From David Rumsey to the DPLA
Genealogists rely on historical maps to help us navigate the geography of our ancestors’ lives. One of the most important resources available online is the David Rumsey Map Collection. Well, Rumsey recently announced on his website that he will be making more than 38,000 of his historical maps–everything he’s currently got online–available at the Digital Public Library of America (DPLA).
I blogged recently about the DPLA, which aims to create an enormous, free digital library we can all access online. It will be great to have the Rumsey map collection searchable on the DPLA so we can search these maps while we look for any other sources on any particular location our ancestors lived. “Maps tell stories that complement texts, images, and other resources found in the growing DPLA library,” says Rumsey. “And the open content policies of my online library fit perfectly with DPLA’s mission to make cultural resources freely available to all.” He applauds what the DPLA is trying to accomplish and even encourages other collectors to donate content.
Rumsey has spent years collecting thousands of old maps and putting them online. Now he’s working to share them even more widely. His entire collection of about 150,000 maps will eventually be housed at Stanford University. Meanwhile, we can all enjoy the thousands of images we can search on his site or at the DPLA.
Google’s free program Google Earth includes nearly 150 historic maps in the Layers panel. You can also add historic maps downloaded from Rumsey’s site to Google Earth by using the Overlay feature. My video tutorial series called Google Earth for Genealogy will show you how. You can also get step-by-step instructions in my book The Genealogist’s Google Toolbox. Or get them all in a discounted bundle.
