Dear list members: I have a question on the ownership of "second-hand" artifacts. Recently I published a paper that displayed samples of Newton's handwriting from Jerusalem library. I paid for each of them in cash:) Now I want to publish another paper in another journal with parts of the same pages displayed again. Should I pay to the same library again (for virtually same pages)? Or should I negotiate the matter with the first journal to dismiss charges altogether? Or? Ari Belenkiy
