Have you ever visited a webpage where you couldn't tell the difference between the home button and the self-destruct button? Have you ever visited a website on your phone that did not have a clear menu to select from? Have you ever clicked on a link that no longer existed? Adhering to accessibility guidelines benefits all users by making sure that everyone has access to the information they need.

Making content accessible is important for everyone, not just individuals with disabilities. Using this Accessibility LibGuide from the Henry Whittemore Library, you can make your content: available to all users, simple to navigate, easy to read and understand, and capable of being adapted to newer technologies. Accessible design is good design!

The guidelines and Success Criteria are organized around the following four principles, which lay the foundation necessary for anyone to access and use Web content. Anyone who wants to use the Web must have content that follows the four principles below.

1. Perceivable - Information and user interface components must be presentable to users in ways they can perceive. This means that users must be able to perceive the information being presented (it can't be invisible to all of their senses)
2. Operable - User interface components and navigation must be operable. This means that users must be able to operate the interface (the interface cannot require interaction that a user cannot perform)
3. Understandable - Information and the operation of user interface must be understandable. This means that users must be able to understand the information as well as the operation of the user interface (the content or operation cannot be beyond their understanding)
4. Robust - Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. This means that users must be able to access the content as technologies advance (as technologies and user agents evolve, the content should remain accessible)

If any of these are not true, users with disabilities will not be able to use the Web.

Under each of the principles are guidelines and Success Criteria that help to address these principles for people with disabilities. There are many general usability guidelines that make content more usable by all people, including those with disabilities. However, in WCAG 2.0, we only include those guidelines that address problems particular to people with disabilities. This includes issues that block access or interfere with access to the Web more severely for people with disabilities.

To write about disability, we need to listen to the voices of people with disabilities. Below, find a few books that can provide perspective on this topic.
