Supporting Web Accessibility with HTML5 and Accessible Rich Internet Applications: Insights for Libraries

Abstract Purpose To provide librarians with a better understanding of what makes online content truly accessible and to increase awareness of the current common accessibility issues found in library web sites and vendor supplied electronic resources. Methodology/approach A through and in-depth literature review takes a look at the web accessibility problems historically found in library web sites. It then briefly explains the basics of web accessibility and delves more deeply into structural content access, which is the hallmark of true accessibility. The simple mechanics as well as the pros and cons of traditional methods of providing keyboard access to web content is discussed. The chapter then provides a gentle introduction to HTML5 and the Web Accessibility Initiative-Accessible Rich Internet Applications (WAI-ARIA), current use, techniques for use, and application opportunities. The chapter also provides the research results of a broad examination of the basic structural accessibility state of many current database providers. Findings The research shows that the accessibility of library web sites is improving; however many library vendor database products still have significant accessibility problems. Practical implications Through the practical accessibility explanations, the chapter points out the ways librarians can use this knowledge to work with users and communicate with product providers regarding the accessibility of library resources. Originality/value This chapter provides a rich resource for understanding and implementing web accessibility, particularly as it applies to keyboard navigation and the new accessibility features in HTML5 and WAI-ARIA.
