A review of the literature separated into the form categories of scientific papers, reports, meetings and conferences, periodical articles, and state publications.

A very thorough Library of Congress bibliography (complete with Library of Congress call numbers) of books and articles on various aspects of conservation as defined in strictly utilitarian, economic and scientific terms. Topically organized (e.g., "General," "Mineral," "Water," "Forests," "Land and Soil," etc.); includes some 600 entries and author and subject indices. Still extremely useful to researchers in these areas of conservation history in this era, this work also suggests how conservation was most clearly defined in the public mind at this time, and the degree to which it had come to assume unquestioned importance in American public policy.
