Accessibility books we recommend

  1. Joe Clark: Building Accessible Websites.
  2. Jim Thatcher et al: Constructing Accessible Web Sites. Less comprehensive than Joe Clark's book, but goes into greater depth in the topics it covers. Gives screenshots of how various screen readers and alternative browsers interpret various tags and mark-up. Also has an amazing chapter on the current state of legal accessibility requirements.
