The Portland Press Herald Still-Film Negative Collection consists of 70 years (ca.1936 - 2005) of primary photographic images, in approximately 425 linear feet. The collection is made up entirely of negatives; there are no prints. Formats include 5x7", 4x5", 120, and 35mm still film, all taken by Portland Press Herald photographers, during the Guy Gannett Publishing era. The Gannett family founded the newspaper in 1921. The collection was salvaged from the Gannett Building (390 Congress Street) and accessioned by the Portland Public Library, from the Portland Press Herald, in December 2009. The collection is owned by the Library, and is currently in the process of being arranged, described, indexed, and conserved. The depth of substance within this collection provides an extraordinary spectrum of real-time documentation of the many-faceted life of the city of Portland through the 20th century.
