The Congressional Office of Technology Assessment closed on September 29, 1995. During its 23-year history, OTA provided Congressional members and committees with objective and authoritative analysis of the complex scientific and technical issues of the late 20th century. It was a leader in practicing and encouraging delivery of public services in innovative and inexpensive ways, including distribution of government documents through electronic publishing. This site honors that legacy by making available in electronic form the complete collection of OTA publications along with additional materials that illuminate the history and impact of the agency.
