Las pautas de accesibilidad antes que las WCAG

Unified Web Site Accessibility Guidelines (enero 1998) son las pautas de accesibilidad que se convirtieron posteriormente en Web Content Accessibility Guidelines 1.0 (mayo 1999). Los dos autores del documento inicial, Gregg C. Vanderheiden y Wendy A. Chisholm, fueron luego editores de WCAG 1.0.

La introducción del documento dice:

The 8 series of website accessibility guidelines is the final set of unified guidelines prepared by the Trace Center. The Web Access Initiative (WAI) of the World-Wide-Web Consortium (W3C) has been launched, and the development of HTML guidelines is being transferred to that body. The Trace Center will be continuing to work with and as a part of the WAI. As a result, the Trace Center will no longer be developing or maintaining this Unified Website Accessibility Guideline series. Readers are referred to the W3C site (http://www.w3.org/wai) for the latest version of the guidelines.
