Some copyright restrictions apply. Within Series 1, newspaper clippings and other published materials dated prior to 1923 and any unpublished materials dated prior to 1889 are within the public domain. All other materials are restricted by copyright. Within Series 2, the daguerreotypes, cartes de visite, cabinet cards, and tintypes are all in the public domain. The dated photographs have entered or will enter public domain 120 years after their creation, these dates ranging from 2004 to 2076. The undated photographs (including the negatives) appear to date to the 1920s and 1930s and so should enter the public domain in 2060 at the latest. However, copyright status of each item should be determined on a case by case basis. Please consult library staff for more information.
