Stephen I don't quite understand why you fear this, but I am not a lawyer and not familiar with US law. I will use other channels for such contributions, if there should be any. As material for Olson's and Eggert's defense I think these quotes of Shanks's sources are relevant. Later (current) editions of the books do no longer mention any sources, only the old editions do. They confirm in writing that Shanks copied most of his data from other published sources. Knowledge of the sources will make it rather easy to clean up TZ files from quotes of Shanks. I think personally that no such cleanup should happen. The lawsuit should be fought and will be won by Olson and Eggert, as their use they make of Shanks' data is fully legitimate.
