As far as I know, there is only one book on SuperCollider published by MIT: The SuperCollider Book, edited by Cottle, Collins, Wilson. There is Introduction to SuperCollider by Andrea Valle, though this is published by Logos Verlag (Berlin).
I would recommend the Book, esp. the first chapter and Kuivila’s chapter on Patterns (if, like me, you’re interested in event patterns). Cottle also has survey on computer music using SuperCollider as its practical framework, freely downloadable here.
