As part of the historic 1998 settlement between the tobacco industry and 46 state attorneys general, tobacco manufacturers agreed to provide public access to industry documents produced through the discovery process through a series of Web sites that the industry would maintain until June 30, 2010.

A year ago, fearing the eventual loss of public access to these documents, the American Legacy Foundation awarded $15 million to the University of California San Francisco to establish permanent Internet access to the documents and to develop a center for scholarly study of the material.
