This article summarizes the findings of a book-length study of how Americans have used information since the 1700s, with a primary emphasis on the post-1870 period. The author argues that residents of North America were extensive users of information in their work and in their public and private lives. Reasons are offered for that dependence on information: high levels of literacy, economic prosperity, open political system, and considerable personal freedom to do as one wanted. The article describes findings on information use in the private sector, public sector, and in private life, including the American experience using the Internet.
