This is a set of papers that describe accessibility issues for users with various cognitive or learning disabilities. Each issue paper takes information from Cognitive Accessibility User Research [[coga-user-research]] and distills it into a description of the challenges for a specific user group or web usage pattern, and suggests ways to address those challenges. This information informs the Cognitive Accessibility Roadmap and Gap analysis [[coga-gap-analysis]] in its identification of which solutions remain unmet at this time. The set of issue papers in this publication is not comprehensive and additional ones may be added to future publications of this document.
