Reading for the lecture on 24th sept

On 24th september we'll be discussing HTML5, in preparation to two Javascript lectures and a HTML-based phone app lecture during october. One OK book to read on this is http://www.manning.com/crowther2/ , but you can consider whether you're interested enough to buy it or just read the free chapters. 

For free documentation, you can also read http://www.w3schools.com/html/html5_intro.asp
