In 1998 the US Congress amended the Rehabilitation Act to require Federal agencies to make their electronic and information technology accessible to people with disabilities. Section 508 was enacted to eliminate barriers in information technology, to make available new opportunities for people with disabilities, and to encourage development of technologies that will help achieve these goals. The law applies to all Federal agencies when they develop, procure, maintain, or use electronic and information technology. Under Section 508 (), agencies must give employees with disabilities and members of the public access to information that is comparable to the access available to others. History Section 508 was originally added as an amendment to the Rehabilitation Act of 1973 in 1986. The original section 508 dealt with electronic and information technologies, in recognition of the growth of this field. In 1997, The Federal Electronic and Information Technology Accessibility and Compliance Act was proposed in the U.S. legislature to correct the shortcomings of the original section 508; the original Section 508 had turned out to be mostly ineffective, in part due to the lack of enforcement mechanisms. In the end, this Federal Electronic and Information Technology Accessibility and Compliance Act, with revisions, was enacted as the new Section 508 of the Rehabilitation Act of 1973, in 1998. Section 508 addresses legal compliance through the process of market research and government procurement and also has technical standards against which products can be evaluated to determine if they meet the technical compliance. Because technology can meet the legal provisions and be legally compliant (e.g., no such product exists at time of purchase) but may not meet the United States Access Board's technical accessibility standards, users are often confused between these two issues. Additionally, evaluation of compliance can be done only when reviewing the procurement process and documentation used when making a purchase or contracting for development, the changes in technologies and standards themselves, it requires a more detailed understanding of the law and technology than at first seems necessary. There is nothing in Section 508 that requires private web sites to comply unless they are receiving federal funds or under contract with a federal agency. Commercial best practices include voluntary standards and guidelines as the World Wide Web Consortium's (W3C) Web Accessibility Initiative (WAI). Automatic accessibility checkers (engines) such as "IBM Rational Policy Tester" and AccVerify, refer to Section 508 guidelines but have difficulty in accurately
