This document provides steps for making comparisons between sources. It outlines identifying common criteria between the sources, examining what each source says and potential inferences, and determining if similarities or differences exist for the common criteria. It also discusses looking at the purpose, audience and originator of each source, precisely defining what is being compared, and considering the tone of the sources. The overall process involves identifying comparison criteria, explaining how criteria are similar or different, questioning the content, and citing evidence from each source.
