Collection Guides (Finding Aids)

The LAVO Photograph collections are described and inventoried in detailed guides, also known as finding aids. Finding aids provide background information on the organization, person, or family who created or collected the photographs, an overview of the collection and its arrangement, and a detailed inventory.
