I've been going through my files trying to close out some partially finished projects. I have several Beatrix Potter books that had missing or damaged pages, and I went to the library today to try to fill in the blanks. Unfortunately, they only had the newer editions with a modern copyright, claiming a copyright because they had made a new transfer of the old watercolors. As far as I understand copyright law, this claim is bogus; a derivative work must be different enough from the original to be considered a new work; a slight technical improvement on the reproduction is not enough. An original lithograph, sure, but not making new screens. This may or may not be complicated by the fact that the publisher operates both out of the UK and the US. Is my understanding correct enough to go through with an official clearance request? Or shall I hunt for older copies? Potter books are not rare, but finding the older ones is more difficult. Thanks, R C
