Kelvin Mason and I have a piece in the forthcoming book The Para-Academic Handbook: A Toolkit for making-learning-creating-acting from HammerOn Press. See the link for a full description of the project.
My understanding is that you can download an e-copy of the book for free starting September 15, which is when the book will be formally released. If you would like a paper copy they can print one for about £18.
Also, the editors have made available an article they wrote to accompany the book’s release, which you can find here.
