WikiBooks, whose motto is “Think free. Learn free.” has a special section called Wikijunior, a project aimed at producing full-color booklets for kids 8-11. The books are being developed and offered online (and some in pdf format). Some books may also go into print. One of the current complete titles is The Solar System. Other Wikijunior books will reportedly follow a similar format. In that these books are available in digital form, they move us toward universal design because the text can be manipulated, printed, or read aloud with text-to-speech.
