Thanks very much to Eric Reiter, Maiju Lehmijoki, Tom Izbicki and George for all the suggestions. I have Aviad Kleinberg's book and should have thought of it of course. Professor Lehmijoki, I'm afraid the books need to be in English or possibly French for my student's purposes. I suspected Woodward dealt with the modern situation but hoped perhaps he goes a bit into the history of canonisation. Thanks again for everyone's help, on behalf of my student as well.
