This presents me with a dilemma. As a courtesy to the gentleman who gave me permission to use the jpegs he's produced of the original PD engravings I've put on the title and copyright page of the book I'm producing something like 'Illustrations © Paul Lewis ...' I'll have to decide whether to take that off when the book is ready for upload. It shouldn't be hard to work out some wording which gives him credit for his hard work, but doesn't say something which is not true. I guess I'll replace the © with 'thanks to' or 'produced by'.
