# NDIIPP Briefing: How Are We "Ensuring the Longevity of Digital Documents?"

David S.H. Rosenthal, chief scientist with the LOCKSS Program at Stanford University, explores sustainable approaches to format obsolescence in digital preservation. He discusses large scale interactions between the evolution of information technology over time and the social, technical, and economic factors that enable digital preservation; changing fundamental understandings of threats and challenges in digital preservation starting from Jeff Rothenberg's 1995 Scientific American article "Ensuring the Longevity of Digital Documents" and moving onwards to the present and the future; and emerging recognition that economic and social sustainability are the overarching long-term barriers.
