  These notes are an extension of the rough notes provided for my four lecture
graduate level course on "Quadratic Forms and Automorphic Forms" at the March
2009 Arizona Winter School on Quadratic Forms. They are meant to give a survey
of some aspects of the classical theory of quadratic forms over number fields
and their rings of integers (e.g. over Q and Z), and their connection with
modular and automorphic forms.
