I have a copyright law issue right now, and I wonder if you could help. There are three splendid books about the rise of Nazism and related issues, published in Britain but by non-British authors: Germany puts the clock back (1937), by the American journalist Edgar Mowrer; The War against the West, (1938) by the Hungarian philosopher Aurel Kolnai; and World in trance (1943), by the German journalist and historian Leopold Schwarzschild. So far as I can see, they are all still under copyright. They are all important works, and none of them have ever been reprinted. I would like to scan them and publish them on a non-profit website, but I have no way to find out who the rightful copyright holders are, and the fact that nobody has ever reprinted anything by these gentlemen strongly suggests that professional publishers cannot do so either. What should I do? Would a strongly worded warning about using the contents of the website for profit, and an appeal to any copyright holder to come forward, be enough?
