How does intellectual freedom in libraries in the 1970s compare with today? Danuta A. Nitecki and Eileen G. Abels, asked Henry Cohen and me to write a chapter in the 30th anniversary edition of Advances in Librarianship.
Henry and I were asked to give a 21st century perspective on two key articles in Advances written in the 1970s: Edwin Castagna's Censorship, Intellectual Freedom, and Libraries (1971) and David Berninghausen's Intellectual Freedom in Librarianship: Advances and Retreats (1979).
Here is our chapter in a preprint form. If you'd like to see the final form complete with citable page numbers, see the Advances in Librarianship site at www.sciencedirect.com/science/bookseries/00652830
