Some more bits I've found:
Some scholars of Tolkien include
Dr Gray at Chichester University and
Josh Bradbury at Bangor University. London Met has a
more cultural studies based class within a wider module, which looks at the films. The
University of Liverpool has a unit where Tree and Leaf is a required text.
But how about
this course at University of Central Lancashire, AKA Preston University? This is the only entire module devoted to Tolkien that I've yet discovered!
