The Oxford Handbook of Algorithmic Music, edited by Roger Dean and Alex McLean, is out and available now. As a teaser, you can download my chapter "Thoughts on An Algorithmic Practice" here:

It's a great collection, with lots of interesting essays. If you are at all associated with a library, you should get your library to order it (like all academic publications, it's 'spensive), and enjoy it in it's full.
