The Library of Michigan Digitization for Preservation and Access Grant was awarded to the Detroit Public Library in 2005. The grant allowed for the creation of a digital database of 19th century and pre-1922 photographs of Detroit. The formats include glass negatives, lanternslides, cased images, albumen prints and stereograph cards from the Detroit Public Library's Burton Historical Collection. These images illustrate the social and cultural history of Detroit as well as document the historical events that have occurred in the city.
