Accessibility Assessment

Although this volume is a collection of works that have (almost) all been previously published, seven key areas related to accessibility were assessed during the importing and editing process. The checklist below has been drawn from the Rebus Guide to Publishing Open Textbooks (So Far), which was itself adapted from the BCcampus Open Education Accessibility Toolkit. While a checklist such as this is just one part of a holistic approach to accessibility, it is one way to begin work on embedded good accessibility practices.
