Part of the Government Information Center The Wallace Stegner Environmental Center Collection, named after the Pulitzer Prize-winning author, seeks to inspire understanding and appreciation of the interconnectedness of life on earth. The collection contains literature concerned with core environmental issues: introductory materials on all aspects of the environment; appreciation of the natural world; conservation strategies; consumer awareness; political activism; business techniques; directories of "green" companies and toxic and hazardous waste handling. The selection of environmental periodicals meets the need for reliable current information. The collection is closely linked to the Library's collection of federal, state and local government documents, which include numerous proceedings, hearings, reports and informational series on environmental topics. The Center's collection is geared towards the interested layperson, local environmentalists, students from middle school through the undergraduate college level, and the San Francisco business community. The collection is weeded continuously based on use.
