To know the Digital Library of South Dakota (DLSD) is to explore the wide world of this majestic state and its rich history. The DLSD is a collaboration of the libraries of the six Board of Regents colleges and universities, along with other educational partners around the state. On the site's homepage, visitors can elect to search across all of the DLSD collections or use the "Browse" feature. There are about three dozen collections available and they include Black Hills National Forest, Institute of American Indian Studies, and the Mahoney Music Collection. The Black Hills National Forest collection is a wonderful tour through the history of this regal national treasure, complete with dramatic historic vistas and the gorgeous Bridal Veil Falls. There's much more to explore here and overall it's a nice model of interinstitutional cooperation married to a wealth of diverse resources.
