«The goal of Elephind.com is to make it possible to search all the world’s online historic newspapers from one place. We aren’t there yet, but we are adding more newspapers every day.
With Elephind.com it is now possible for family historians, genealogists, and researchers to search historic digitized newspaper archives from around the globe. Elephind.com is much like Google, Bing, or other search engines but is focused on only historical, digitized newspapers. It enables you to search, for free, across many newspaper sites simultaneously, rather than having to visit each site separately. By clicking on the Elephind.com search result that interests you you’ll go directly to the newspaper site which hosts that story.
Many of the smaller newspaper sites are not well known and may be difficult to find with the usual search engines but are searchable from Elephind.com.»
