Similar question was already asked at Problem with bibliography with the MITWPL style template but it appears the mitwpl.cls file at http://mitwpl.mit.edu/publish/#template has been updated and the solution no longer works.
The problem with the template is that the .tex file won't compile for the following issue:
! LaTeX Error: Command \bibfont already defined.
Does anyone know how to fix the original stylesheet or has an updated version? Thank you!
