I have here a copy of The Strange Case of Dr Jekyll and Mr Hyde by Robert Louis Stevenson, republished in 2010 by Harper Press, an imprint of HarperCollins's. On the copyright page is this text, with no further explanation:
Robert Louis Stevenson asserts the moral right to be identified as the author of this work
(See Wikipedia on moral rights for an explanation of the right allegedly asserted, and of the alleged assertion.)
I find it hard to believe that Stevenson asserted any such thing.
The Berne Convention, which standardized such rights, wasn't agreed to until 1928, long after Stevenson's passing.
Wikipedia does indicate that France and Germany had such rights earlier, though it doesn't indicate how much earlier. Stevenson lived in the United Kingdom, but I suppose it's possible that he asserted his moral right for effect on the Continent. Or perhaps he happened to write "I insist on being called the author of that book" to his publishers before anyone was discussing moral rights at all.
Can HarperCollins's claim be substantiated or disproven?
