I've downloaded problem sets for the course Math 112 of 2001--2002 at the Harvard Mathematics Department. In some of the problems, there're references to a certain book, but since there is no syllabus to accompany those problem sets, I'm unable to figure out which book that is.
I know that nowadays they're using Baby Rudin for the same course. Which text were they using back then? And, where can I get complete course materials from that particular year and those following and preceding it?
Regards.
