Environmental Protection Agency’s (EPA) library network provides staff and the public with access to environmental information. Its 26 libraries contain a wide range of information and resources and are located at headquarters, regional offices, research centers, and laboratories nationwide. In 2006, EPA issued a plan to reorganize the network beginning in fiscal year 2007. The plan proposed closing libraries and dispersing, disposing of, and digitizing library materials. GAO was asked to assess (1) the status of, and plans for, the network reorganization; (2) EPA’s rationale for reorganizing the network; (3) the extent to which EPA has communicated with and solicited the views of EPA staff and external stakeholders in conducting the reorganization; (4) EPA’s steps to maintain the quality of library services after the reorganization; and (5) how EPA is funding the network and its reorganization. For this study, GAO reviewed pertinent EPA documents and interviewed EPA officials and staff from each of the libraries.
