I recently looked through my emails and added up the number of books on the subject of Janet Frame's work that are currently on the drawing board, and found that as far as I know, there are at least half a dozen underway. (There may well be more!) Here's a link to the cover art that will appear on one of these volumes:
Janet Frame: Semiotics and Biosemiotics in Her Early Fiction by Paul Matthew St. Pierre (Fairleigh Dickinson University Press, New Jersey, USA, forthcoming 2011).
French academic Claire Bazin has also completed a study on Janet Frame for the Writers and Their Work series published by Northcote House Publishers, UK.
