Huprich, Julia Public Libraries Access to Information Web Sites Design Requirements Guidelines Electronic Mail Mail Surveys Disabilities Accessibility (for Disabled) Assistive Technology Delphi Technique One issue that public librarians must consider when planning Web site design is accessibility for patrons with disabilities. This article reports a study of Web site accessibility of public libraries in Georgia. The focus of the report is whether public libraries use accessible guidelines and standards in making their Web sites accessible. An e-mail survey asked each of the 58 library systems to respond to statements that propose accessible guidelines. The authors decided to follow up the survey by using the WebEXACT tool to corroborate the survey and to provide more specific information about the modifications that are needed. This tool offers suggestions for accessibility that should serve to decrease the number of pages that are inaccessible to patrons. The results from the survey and from the WebEXACT check both indicate many strengths as well as weaknesses.
