Known Accessibility Issues and Areas for Improvement
- The “Chapter Reflections” at the end of each chapter occasionally link to YouTube videos created by other people. Many of these videos only have automatic captions and do not have audio descriptions. These are additional resources and not a part of the core content of the text.
- Some links to PDFs do not have “PDF” included in the link text. This is mostly confined to the attributions and reference section at the end of the chapters.
