At Yale University and the library we strive to follow the AA standards of the W3C Web Content Accessibility Guidelines (WCAG) 2.0. Making your web site accessible means your online resource is usable by the widest variety of people possible, including those who use screen readers, cannot use a mouse, or who may be on a slow wireless connection. The User Experience group recommends library web site and subject guide creators review the guidelines listed here so that you understand the major components of web accessibility. Following basic accessibility guidelines will ensure that your web site is coded accurately for meaning and that it will be rendered well in a variety of formats.
When you create an individual web site or subject guide you use tools (Yale's Drupal service and Libguides), which when used correctly will produce highly accessible pages. Simply using the color schemes defined in the library's YaleSites and Libguides implementation, and following the system prompts when creating pages and forms will ensure a high-level of accessibility. You can use the simple checklist provided here to ensure that you have not introduced any inaccessible elements.
What follows is a brief guide to help with some of the most important accessibility rules. If you are creating a more complex web resource you should contact the UX Group for a more in-depth review.
