Grüß Gott to our students in Switzerland! I want you to know that even though I am physically and temporally somewhat far away, you should still feel free to call on me for assistance with any research for your classes. Our online resources are extensive and top-of-the-line, and accessible, obviously, everywhere and at any time. The library is no longer a static place, we are an anywhere and anytime resource!
