Since 2016, each issue of the American Historical Review has included a short list of websites that contain freely available digital primary sources. This website reproduces that list (with minor edits), including the site's geographic category as it appeared in the AHR and brief blurb associated with each site.
Broer Map Library: Online Historic Maps
A growing collection of thousands of online historic maps from around the world.

Users may also search the Historic Map Index, which includes information about 60,000 historic maps in over 100 other online collections.
