This report is concerned with the literature and library service requirements of the United States Environmental Protection Agency (EPA). It presents the findings and recommendations produced during a nationwide survey of EPA employees. Engineers, physical and biological scientists, administrators and managers, lawyers, and social scientists are represented among the randomly selected sample of employees actually contacted. All levels of civil service involved in Agency activities are included; so, too, are all regional offices, research centers and headquarters, along with a small number of the Agency's remotely located facilities.
