In a 2009 "Computers and Composition" article, I examined how the terms multimedia and multimodal were used in academic and industry situations. This webtext extends that argument to investigate the ways in which a variety of other terms, including digital media and new media, are defined by scholars in the fields of computers and composition and education. These interview-based conversations laid the framework for a broader consideration of the anatomy of a definition: how we develop definitions and how definitions shape our work in academia, the classroom, and public life.
