TurnItIn (2012) The Plagiarism Spectrum: Instructor Insights into the 10 Types of Plagiarism,
TurnItIn, the creator of anti-plagiarism software, has produced a useful if somewhat picky report on different types of plagiarism. Useful comments from Jonathan Bailey in Plagiarism Today. It is important to differentiate between different types of plagiarism and their relative importance, and there are some useful guides on how to deal with the issue in Jonathan Bailey’s article.
One category that amused me was ‘recycling’, i.e. re-using one’s own previous work without attribution – guilty, m’lud!
Now is my copy of part of the TurnItIn graphic plagiarism or breach of copyright (or fair dealing)?! I’m seeking guidance from my legal department.
Thanks to Stephen Downes for directing me to this (sorry about the plagiarism, Stephen).

Let he without sin cast the first stone.
Should I have quoted that?
How is “Find/Replace” so low on the “problematic” scale??? There are some strange ratings here!
Is this part of the white paper linked above? What was the process used to produce it?
Hi, Pete
Yes, the graphic is from the white paper produced by TurnItIn, which also describes the method (mainly interviews with faculty).
Good list, remember back in college once hearing “if you quote one source it’s plagiarism, if you quote two it’s research”…
