NEDCC (Northeast Document Conservation Center)

“Founded in 1973, NEDCC is the first independent conservation laboratory in the nation to specialize exclusively in treating collections made of paper or parchment, such as works of art, photographs, books, maps, manuscripts, and more. The Center
offers conservation treatment, digital imaging, and audio preservation services, as well as training, consultations, and  disaster advice for collections.”
