My forthcoming book, Effortless Flex 4 Development, is now available to be read online through Safari Books Online. The direct URL is http://my.safaribooksonline.com/9780131389465. Through that site you’ll be able to read the book as I write it and make comments on the work. Frequently those comments can be used to fix or improve the finished version of the book. Note that Safari Books Online is a paid service but there is a free 10 day/100 page trial.
