Irreducible Modular Representations of
Finite and Algebraic Groups Notes by Christopher Drupieski and Terrell Hodge,
based on lectures by Leonard Scott.
The organizers have begun a wiki with a bibliography and reference
material, located at http://modularrepresentations.wetpaint.com/.
That wiki is viewable by anyone and can easily be edited.
