"The NSSN National Resource for Global Standards contains over 250,000 references to standards from more than 600 national, foreign, regional and international bodies worldwide. This, the free version, searches approved industry standards, approved international standards (ISO, IEC, ITU), approved U.S. government standards, and the American National Standards Institute (ANSI) catalog. Users can search by standard number, title or abstract, and can limit the search by the developing body/ies or committees. There is also the option to search regulatory references to voluntary standards from the Code of Federal Regulations (CFR). The records provide brief descriptions of the standards and provide links to purchase electronic or print versions of the full text. This is a very useful discovery tool for national and international standards"--Reviewed Mar. 25, 2004, "Best Free Reference Web Sites 2004," RUSA Quarterly, Fall 2004.
