From the longer Wikipedia page [1] The National Public Broadcasting Archives (NPBA) – housed as part of the Broadcasting Archives at the University of Maryland – preserves the history of American non-commercial broadcasting materials. It is housed at the University of Maryland, College Park in Hornbake Library. NPBA serves as a living reminder of the cultural and intellectual continuity of the effort to make television something more than commercial networks can provide. Its mission is to work with the primary national entities of American noncommercial broadcasting to identify records and programs of historical value and to serve as a repository for those materials. Its collection is open to the public.
