Bodman and Sowden's book, A manifesto for the book, was published online this year following a research project funded by the Arts and Humanities Research Council.
To quote from the web page cited below, "This project investigated and discussed issues concerning the context and future of the artist’s book, in an attempt to extend and sustain critical debate of what constitutes an artist’s book in the 21st Century".
