This paper provides guidance on the issue of universal Web accessibility for individuals with physical challenges, who need accommodations to fully participate in the electronic world. Four categories of information facilitate understanding the complexity of the issues. These categories are: U.S. legal mandates; international accessibility policy and legislation; resources and information; and Web site accessibility validation. These four categories are explored in depth and provide the tools for meeting today's challenges. As the Web evolves, new accessibility issues will emerge. (Contains 12 references.) (Author)
