Beginning May 1, 2019, the HCC Libraries automation librarians began systematically testing LibGuides and pages for WCAG 2.0 compliance using the WAVE Accessibility tool as a Chrome plugin. The Library site contains over 150 librarian-published LibGuides consisting of multiple pages and content types.
"WCAG 2 level AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, and a contrast ratio of at least 3:1 for graphics and user interface components (such as form input borders). Level AAA requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text."
Coming soon. See the sections above for Articles, Books, and eBooks.

From the Institute for Human Centered Design
Compiled by advocates of Universal Design in 1997. Participants are listed in alphabetical order: Bettye Rose Connell, Mike Jones, Ron Mace, Jim Mueller, Abir Mullick, Elaine Ostroff, Jon Sanford, Ed Steinfeld, Molly Story, Gregg Vanderheiden. The Principles are copyrighted to the Center for Universal Design, School of Design, State University of North Carolina at Raleigh [USA].
The Principles established a valuable language for explaining the characteristics of Universal Design. They are in common use around the world, sometimes with slight modifications, primarily one or two principles grouped together.
