This is that rarest of things, a book you not only read, but keep perched on the edge of your desk for reference. Susi has created the definitive translation and guide of the WCAG standards for L&D professionals. Having these guidelines, that often feel like they were deliberately written to be unintelligible, translated and explained in plain English is an invaluable resource for creating genuinely accessible experiences. This second edition builds on the success of the first, clarifying, distilling and expanding to include new success criteria. This is the book I ensure every member of my team has to hand. If you work in L&D, create digital content, or are simply interested in accessibility, you need to read Susi's book asap.
