I've just received an offer to write a chapter for a book that will be published with an important publisher. I was about to say yes, because the topic fits with my dissertation topic and I thought I could use it for my paper-based dissertation, but a colleague told me that a chapter in a book may not be considered for a paper-based dissertation. What was your experience? Do you know anything about it?
Update: Finally my Uni will accept a book chapter as part of my paper-based dissertation. I had to argue that even though it was a book and not a journal, the chapter (actually the whole book) will be reviewed by at least two reviewers. Thanks for your answers!
