This Directory is based on a survey of 1,234 federal libraries and information centers in the 50 states and the District of Columbia conducted in 1994. The survey was developed and funded by the National Center for Education Statistics (NCES) with the advice and guidance of a survey working group of the Federal Library and Information Center Committee of the Library of Congress and was conducted by the U.S. Census Bureau. The Directory is organized by branch of government (Legislative, Judicial, or Executive), by agency in the Legislative and Judicial Branches and by department in the Executive Branch. Within each department, agencies are listed alphabetically and within the agency, libraries and information centers are listed by state with the states arranged alphabetically. Each library and information center has four entries: its name, its address, the name and telephone number of a contact person, and the type of library or information center. The type of library or information center represents the library's or information center's primary subject-matter acquisitions. The following types of libraries and information centers are used in the Directory: presidential, national, academic, engineering and science, health and medicine, general, law, multi-type, training center and/or instructional technical school, and special.
