This document provides an overview of the BEAM framework for evaluating and categorizing sources. It defines each element of BEAM - Background, Exhibit/Evidence, Argument, and Method - and provides examples of source types that fit within each element. The document encourages using sources in writing to provide context, basis for analysis, understanding of how topics have been discussed by others, and information for conducting own analysis. It suggests databases for finding sources corresponding to each BEAM element for debate topics or experiment topics. In the end, it poses questions and provides contact information for the presenter.
