Millions of library books are literally turning to dust because of acid. Only recently has the papennaking industry attempted to restore product pennanency by producing acid-free and • alkaline buffered papers. American publishers are showing a greater interest in such pennanent papers. However, the transition to acid-free alkaline buffered paper by publishers has not been adequately monitored or surveyed. The 1989 pH investigation of 1987 acquisitions at Brigham Young University provides an in-house reference point for future monitoring and indicates that many publishers use acid-free and alkaline papers. The BYU survey and test model are designed for easy replication.
