Books, Sites, and Guidelines on Accessible Web Design

Contents

What Is On This Page

The books listed below are not necessarily introductions to HTML, CSS, and JavaScript. Moreover, they are books aimed at developers who already have some experience coding web pages and project managers and administrators who need to be informed about accessibility, solid usability principles, and web standards.

If you need a gentle, no-nonsense, up-to-date book teaching HTML and CSS with full awareness of web standards, the WAC highly recommends the clear and well-paced Spring Into HTML and CSS by Molly Holzschlag (Addison-Wesley, 2005).

As with the books, our selection of sites and centers is not meant to be comprehensive. Instead, we have tried to choose resources that will aid and inspire web developers. And since accessibility might be considered usability for people with disability, it made sense to include a couple of resources focusing on usability.

The guidelines and guides listing covers the expected standards and some perhaps not so expected development guidelines. We also include a reference to a list of higher education institution accessibility standards and statements.

Books

Sarah Horton, Access by Design: A Guide to Universal Usability for Web Designers (Peachpit Press, July 2005)
A great short book that, like WCAG 2.0, emphasizes design principles over checkpoints. As in the best books on accessibility, usable design is foregrounded. Horton advocates a gestalt of usability and accessibility she terms "universal usability". Contains a ton of good examples from real web sites. Horton has created a full-text online version of Access by Design, complete with illustrations, code examples, and secondary sources.
Shawn Lawton Henry, Just Ask: Integrating Accessibility Throughout Design (Lulu.com, 2007)
By Shawn Henry of the W3C Web Accessibility Initiative (WAI), Just Ask is available online or in print. The book concentrates on ways to include accessibility throughout the entire design process and has very valuable information on evaluation of resources, usability testing with people with disabilities, and even hiring developers.
Andrew Kirkpatrick, Jim Thatcher, Richard Rutter, Cynthia Waddell, Christian Heilmann, Bruce Lawson, and other contributors, Web Accessibility: Web Standards and Regulatory Compliance (Friends of Ed, 2006)
Experts cover many technologies (Flash, PDF, JavaScript, HTML, and CSS) and review U.S. and international accessibility laws and policies. A crucial update to a classic accessibility text.
Joe Clark, Building Accessible Web Sites (New Riders, 2003)
Clark was one of the key people involved in advocating video captioning in mainstream media. Ranging through page structure and layout, font choices, use of images, and multimedia, with a nice chapter on law, Clark's advice is clear, informed, and has the ring of being definitive.
John Slatin and Sharron Rush, intro by Jacob Nielsen, Maximum Accessibility: Making Your Web Site More Usable for Everyone (Addison-Wesley, 2002)
The first part of the book attempts to layout a working definition of accessibility, discussing goverment and public guidelines, law, and policy (Slatin is an editor of WCAG 2.0). The section contains a number of enlightening case studies. The second part of the book focuses on ways to design within guidelines layed out in the first part of the book. It looks at how to write good text alternatives for images and for captioning of multimedia, how to author accessible HTML forms and tables, and how to make PDF accessible. It also discusses the levels of accessibility in various media players and plugins. Some of this latter information is partly out of date, as is the section on CSS. But book is still an excellent reference.
Jim Thatcher, et al. Constructing Accessible Web Sites (Peer Information Inc., 2002)
One of the first books on the subject of accessible web design. Still an excellent resource, with chapters by experts covering law, design tools, current and emerging technologies, in addition to solid code examples.
37Signals, Defensive Design for the Web: How to Improve Error Messages, Help, Forms, and other Crisis Points (New Riders, 2004)
Usability and accessibility often implode dramatically when they are needed most: in filling out forms, in displaying page error messages, and in providing search capabilities. 37signals' book provides cogent annotated examples of poor and solid solutions to these and other typical crisis points, drawn from years of design experience.
Steve Krug, Dont Make Me Think: A Common Sense Approach to Web Usability (New Riders, 2006, Second Edition)
Highly concise and approachable book on usability with a terrific short chapter on accessibility, containing one of the most rational and salable approaches to the topic. Those of us obsessed with accessibility often propose that making a site more accessible will necessarily make it more usable. Though often true, this is not always the case. Alternatively, Krug advises that making sites more usable for the rest of us is one of the most effective ways to make them more effective for people with disabilities.
Dan Cederholm, Web Standards Solutions: The Markup and Style Handbook (Apress, 2004)
Practical examples dovetailing standard markup and CSS with incisive commentaries on when and how to use stylesheets and appropriate uses of HTML to improve accessibility and usability.
Dan Cederholm, Bulletproof Web Design: Improving Flexibility and Protecting Against Worst-Case Scenarios with XHTML and CSS (New Riders, 2006)
Solid solutions for a range of common design techniques, including fluid and multi-column CSS-based layouts, scalable and elegant site navigation, and use of the CSS float property page-level layout.
Jeffrey Zeldman, Designing with Web Standards (New Riders, 2003)
Occasionally idiosyncratic but undeniably important, solid, future-directed advice from one of the major advocates of web standards.
Eric Meyer on CSS (New Riders, 2002) and More Eric Meyer on CSS (New Riders, 2004)
Meyer's books are a terrific advanced introduction to the potential of CSS for the implementation of accessible, usable, and elegant web design.
Stuart Langridge, DHTML Utopia: Modern Web Design Using JavaScript and DOM (SitePoint, 2006)
Many of the solutions in this book are not necessarily accessible, but the general approach, called "unobtrusive JavaScript", is pointing in the right direction: Use the DOM to add listeners to elements you want to assign JavaScript functionality and guarantee that non-compliant browsers or people with no or limited access to JavaScript-enabled elements still can use your page and get to all of your content.
Jeremy Keith, DOM Scripting: Web Design with JavaScript and the Document Object Model (Friends of Ed, 2006)
Provides a nice introduction to JavaScript and then goes on to give many solid (and many potentially fully accessible) examples of using unobtrusive JavaScript techniques to add functionality to you web pages.
James Edwards and Cameron Adams, The JavaScript Anthology: 101 Essential Tips, Tricks, and Hacks (SitePoint, 2006)
A great book by one of the leading figures in accessible JavaScripting (James Edwards, a.k.a., Brothercake). Chapter 16, "JavaScript and Accessibility" is essential reading for developers concerned with accessibility in "Web 2.0".

Sites and Centers

Web Accessibility in Mind (WebAIM)
Current developers of one of the best accessibility checkers (WAVE), WebAIM is a project begun at Utah State University's Center for Persons with Disabilities but has become one stop shopping for everything regarding web accessibility—design, training, advocacy, et cetera. WebAIM has one of the most clearly written, usable, and extensive sets of accessibility-centered tutorials on the web.

Guidelines and Guides

OSU Web Accessibility Policy
Implemented June 30, 2004, contains OSU's Minimum Web Accessibility Standards (MWAS). There is also WAC material on MWAS.
W3C Web Content Accessibility Guidelines Version 1.0 (WCAG 1.0)
The current World Wide Web Consortium recommendation.
W3C Web Content Accessibility Guidelines Version 2.0 (WCAG 2.0)
These guidelines move away from laying down rules and toward general principles, an approach that some have found problematic. The new guidelines state that web sites should be "POUR": Content must be Perceivable, all interfaces must be Operable, content and controls must be Understandable, and coding and technologies used must be Robust in order to accommodate current display technologies with an eye toward forward-compatibility. Shawn Lawton Henry has presentation on WCAG 2.0 that covers differences from version 1.0. She recommends the WCAG 2.0 Quick Reference as a good place to start with 2.0.
Section 508
Covers all parts of the redraft of the Federal Rehabilitation Act that introduced requirements for electronic media. Section 1194.22 of US 508 applies to web sites and web-based applications.
iCITA Web Accessibility Best Practices
The Illinois Center for Instructional Technology Accessibility has put together an excellent guide to web best practices that emphasizes functional accessibility. Often web sites are repaired to meet technical specifications that are supposed to make them more accessible. The reality is that such technical repair may do little to make web sites functionally usable to people with disabilities. iCITA's best practices guide focuses on functional accessibility and gives numerous explanations and code samples.
Side by Side, 508 and WCAG 2.0
Jim Thatcher's comparison of US 508 and WCAG 2.0 with a link back to his original work comparing 508 with WCAG 1.0
Disability Discrimination Act information from Webcredible
The UK enacted the section of the DDA covering accessible web sites in 1999 and Australia has a similar piece of legislation. Unlike the US 508 guidelines, private as well as public organizations must conform to the provisions of the Act. It is likely similar law will be enacted in the US in the next few years, perhaps as amendments to Section 255 of the Telecommunications Act. A UIAccess article surveys US legal activities on web accessibility.
W3C Web Accessibility Initiative (WAI)
An excellent resource for high-level overviews of several areas impacting accessibility, including evaluating and managing accessibility within a business or organization. The sections under "Managing Accessibility" will be of interest to web managers and developers. See especially the sub-section on developing a business case for accessibility.
Guidelines for Accessible and Usable Web Sites: Observing Users Who Work With Screen Readers by Mary Theofanos and Janice Redish, reprinted with permission from the ACM journal Interactions, November-December 2003
Usability study of blind users accessing a number of web pages, filling out forms and performing set tasks via screen readers (JAWS and Window-Eyes). Article contains analysis of the observations and a series of guidelines for developers. Some of the other sites on this page contain case studies, as well, but this article gives a good overview of what access is like for people reliant on screen readers.
Web Style Guide
Co-authored by Sarah Horton, whose book Access by Design is referenced at the top of this page, the Web Style Guide used to be the Yale Web Style Guide, but however one refers to it there is little doubt that it is one of the most comprehensive guides available. Sections cover site, interface, and page-level design, typography, multimedia, graphics, and editorial style. Most sections of the online book contain discussions of accessibility.
FAME (Faculty and Administrator Modules in Higher Education)
Users can browse or work sequentially through units covering web accessibility, universal design in learning environments, faculty and teaching staff rights and responsibilities to students with disabilities, and overcoming literacy challenges. Learning modules are geared toward teachers and administrators. Multi-modal presentation throughout—HTML, video with audio and transcript.
Research-Based Web Design and Usability Guides
US Department of Health and Human Services guidelines for authoring of web pages. Includes commentaries on accessibility, navigation, and writing, among many other topics. All of these guidelines are available in their full versions only in PDF, but an older, less complete, HTML version of the guidelines is still available and provides much useful and succinct information. These guidelines are each rated by researched evidence of their effectiveness. They are geared toward research-focused web sites, but the principles they promote are universally applicable in almost all cases.
