As of June 2011, all PDF versions of books published by the National Academies Press (NAP) will be downloadable to anyone free of charge. This includes a current catalog of more than 4,000 books plus future reports produced by the Press -- publisher for the National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council.

The National Academies are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and the world. They produce groundbreaking reports that have helped shape sound policies, inform public opinion, and advance the pursuit of science, engineering, and medicine. NAP predicts that that the new policy will enhance dissemination of PDF reports from about 700,000 downloads per year to more than 3 million by 2013.
