As a result of a presentation at an archival meeting back in January, we’ve been deeply pondering and exploring ways to use social media to drive some Internet-based traffic back to our SCA site and the 100,000 (or so) pieces of digital content we provide access to there. Historypin.com seems like a natural. It is a British site that promotes imagery that reflects local history. It is map-based, and so users can browse around the world for image and document data, or they can search by place name. In joining Historypin, we are in the company of quite a few libraries, museums and archives loading quality material to the Historypin map. Our initial offering to Historypin revolves around two collections on our “channel” [http://www.historypin.com/channels/view/53522/#!photos/list/]. The first is an artificial collection called “Route 66 in the Southwest” that features images from a variety of photographic collections (including: A. H. Clark, Libby Coyner, R. Sean Evans, David F. Finney, Fronske Studios, Gary Gustafson, Joseph Muench, Kathleen Schmand, John Running and Tyler Wade), and covers the Kansas to California geography of the road, circa 1930s-present. Our second collection is comprised of river-running images on the Colorado River in the Grand Canyon drawn from the Margaret Eiseman Collection covering Navajo Bridge to Lake Mead, circa 1953-1974. The Eiseman material is compelling as it includes imagery of Georgie Clark, Mexican Hat Expeditions and the Eiseman’s own dory-based 42 day marathon runs. It covers a significant period in river running history starting with the pontoon boats of Clark, the cataract boats of Gay Staveley and Mexican Hat, and the very growth of river running as an industry that pitted private parties like the Eisemans and their dories against the commercial operators for space on the river and the beaches throughout the canyon. For now, we have loaded a representative sample for the collections from our digital archives, linked appropriate related oral histories to a few images and we are now going to sit back to see what happens over the next 6 months or so. We’re in our sixth week on Historypin, and have almost 600 hits on our 150 images- or about 14 hits per day. We’ll keep you posted on our social media adventures.
