The University of Pittsburgh Library System (ULS) has embarked on a project to digitize and make freely available the holdings of the Darlington Memorial Library. The Darlington library comprises material, such as books, manuscripts, maps, atlases, broadsides, and photographs, and the collection focuses primarily on early American history, especially as it pertains to Western Pennsylvania and the Ohio Valley. The Darlington collection holds eleven of the thirteen Indian treaties printed by Benjamin Franklin at his shop in Philadelphia between 1736 and 1762. Also, a cornerstone of North American exploration, namely, A Journal of the Voyages and Travels of a Corps of Discovery, is part of the library. Published in Pittsburgh in 1807, the author of the book, Patrick Gass, was a member of the Lewis and Clark expedition. As contents of the Darlington library become digitized, the ULS will contribute these resources to the Internet Archive as well as through its own web portal. As a member of the Open Content Alliance, the ULS is helping to build an open and permanent library of multilingual digitized text and multimedia content from around the world hosted by the Internet Archive.
