The Conservation Center for Art & Historic Artifacts (CCAHA), located in Philadelphia, Pennsylvania, was founded by Marilyn Kemp Weidner in 1977, with funding from the National Endowment for the Humanities and in response to the growing problem of paper deterioration occurring in archives in the Mid-Atlantic region. Currently one of the largest nonprofit paper conservation facilities in the country, CCAHA specializes in the treatment of art and historic artifacts on paper, including drawings, prints, maps, posters, historic wallpaper, photographs, books, scrapbooks, and manuscripts, as well as related materials like parchment and papyrus. CCAHA serves cultural, research, and educational institutions, such as museums, libraries, archives, and historical societies, both in its region and across the country. It also works with individuals and private organizations. More information...
