I Hate Books at KnowIT. Miraz explains why books are obsolete and should be replaced with something better.
I provided several links in my post yesterday about WCAG 2. However, the information on this topic is vast. Here are two more.
It’s possible that WCAG 2 could be the new accessibility standard by Christmas. What does that mean for you? The answer: it depends. If your approach to accessibility has been one of guidelines and ticking against checkpoints, you’ll need some reworking your test plans as the priorities, checkpoints and surrounding structures have changed from WCAG 1. But if your site was developed with an eye to real accessibility for real people rather than as a compliance issue, you should find that there is little difference.
