"In response to what I perceived as a lack of accessible guides to theory, I created my own, online Guide to Critical Theory (http://www.cla.purdue.edu/english/theory/). Critical Theory: The Key Concepts represents the most up-to-date version of any material found on the web site (which makes up less than a fifth of this book and where one can still go for additional material). Almost every entry in the online Guide to Critical Theory has been updated or expanded in some way for this book"-- Author's note on use.
