Online Historical Images Roundup from the ACRL

The newsletter of the Association of College and Research Libraries this month offers a terrific roundup of websites with deep collections of historical primary source images online. Relevant to PNW history are the Alaska Digital Archives, the University of Washington Digital Collections, and Calisphere ("a free online collection of more than 150,000 digitized primary materials contributed by libraries, archives, and museums from all over California"). It is from Calisphere we get the image below, "Bridge over Spokane River, downtown Spokane, Washington" [undated].
