Collecting and editing these essays was a lot of (fun) work. But all of the essays in the collection are in the public domain and freely accessible. For that reason, I not only put all of the essays (except my introduction) on this website. And also, the pdf version of the book is free to download below.
But if you really want to support me and the project, I'd appreciate your purchase of the book (in paperback or ebook, both reasonably priced) through either draft2digital or amazon.com. (Buttons below.) Otherwise, the free pdf is available to see and download below.
