Now for the really cool part of the day—a trip to the AIM Library. When David Farmer announced that we were going to tour the AIM library after lunch, I assumed that we were going to be led over the book shelves in AIM. Instead, we went downstairs to a beautiful library were the "real books" were housed. We were able to view rare mathematics books, some of which were printed in the 15th century. Notice the author on the title page of the book in the first photo below. Really cool!!!
