There are more references that we have used in examining the incidence of plagiarism, but we we think the ones listed below reveal the character and context of plagiarism.
This is a set of resources, beyond the primary sources of Howard, Robillard, and McKenzie, that we found helpful for understanding the character and dimension of the problem of plagiarism, for strategies to use in developing more effective assignments, and web resources to help students in understanding plagiarism and ways to avoid being labeled as a plagiarist.
Howard's 2001 "Forget Plagiarism, Just Teach" and the book with Robillard.

This engaging talk shows why a lot of people cheat a little bit with a “personal fudge factor,” and how cheating diminishes when people are reminded of their own “honor codes” and the influence of group affiliation on incidence.
