Hello, I am looking for some assistance finding classic papers in physics. Specifically I am trying to track down Lorentz' paper of 1899 in which he first published the Lorentz transformations, and I am also trying to find Schrodinger's original papers in QM. I have An undulatory theory of the mechanics of atoms and molecules, and I'm looking for the other 3. If they aren't on the web anywhere, then I would like to know if they are in books of collected papers that I can order. Thanks in advance.
