I recently received an email publicizing the digitized Klaus Stopp Collection at the Newberry Library and thought other members might be interested too. It includes approximately 1350 quite beautiful German American birth and baptismal certificates from about 1700 through 1900. See http://publications.newberry.org/digital/stopp-certificates/index.
Readers of H-Rural may be interested in some of the posts appearing lately in the Museums of Minnesota blog on H-Midwest. Many of them are coming from county historical societies in the state. Curators and archivists have been sharing documents and photos from their collections that tell histories from the area that are largely tales of rural life in the upper Midwest.
