To combat recent censorship of national parks in the United States, we have pulled on the resources of the library world to tap into the deep public affection for the National Parks and preserve these targeted materials. We brought together librarians and public historians with data and geospatial experts to create Save Our Signs (SOS), which invites members of the public to visit NPS sites and take photos of interpretive signs. Since we launched our project in July 2025, we have received over 15,000 photos from 422 national park sites. We have used these submissions to create a people’s archive which contains photos of regular NPS signs, alongside documentation of censorship (such as photos of blank spaces where signs used to be), and of creative resistance (such as photos of handwritten signs community members posted at the President’s House site saying “History is real” and “Learn ALL history.”)
