Bailey, J. (2012) TurnItIn Analyzes the Spectrum of Plagiarism, Plagiarism Today, May 10

Online Plagiarism Checker (2021) Guide to Prevention of Academic Plagiarism, July 2

Ryerson University has an open access online game, Academic Integrity in Space, that addresses different topics related to academic integrity, including plagiarism, cheating and group work.

TurnItIn, the creator of anti-plagiarism software, produced in 2012 a useful if somewhat picky report on different types of plagiarism and what academics thought were the most problematic forms of plagiarism. Unfortunately, the TurnItIn post is no longer available, but Jonathan Bailey’s report on it is still online in 2022.

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.

The Online Plagiarism Checker explain[s] how to avoid plagiarism in academic writing and what methods are implemented by college professors to detect it.

One of TurnItIn’s categories 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 the TurnItIn resource (sorry about the plagiarism, Stephen).

Plagiarism is serious, though. Everyone’s work should be properly recognised, and claiming someone else’s ideas as your own is a form of theft.


  1. 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?
