Portland Public Library's Digital Commons is an open-source, online portal featuring digitized materials that represent and preserve the history and community life of Portland, Maine. We are continually adding to these collections of maps, photographs, prints, periodicals, audio files, and various printed texts. These materials are drawn from the Library’s own Special Collections & Archives. In addition to the links on this screen, please make note of the "Local History Collections link," which comprises a variety of additional archival series. There is also a link to the art works displayed in the Library building.
