I'll see what I can find out - it might be worth starting by checking the PRO indexes. Unfortunately I won't be able to travel to Kew (not that it's very far!) for some time as I'm about to be engulfed in exam scripts. When I was last at the Chancery Lane branch of the PRO (before everything was moved to Kew) I sifted through several boxes of stuff on the '15 but didn't come across any such lists as are mentioned - maybe they have been collected since (It was several years ago). As for the book, I suppose it's long out of print & I'm none too sure where to start looking - Bob, have you any ideas? I suppose I might contact the publishers, who I believe are still in business under the name Routledge Kegan Paul - mainly associated with the R.C. Church. Roger Later:- I've e-mailed the P.R.O. enquiry desk & hope for a reply this year, next year, sometime, never!
