Types of Plagiarism

Plagiarism is not always a black and white issue. The boundary between plagiarism and research is often unclear. Learning to recognize the various forms of plagiarism, especially the more ambiguous ones, is an important step towards effective prevention.

The Plagiarism Spectrum was developed as a way to define and distinguish the common ways in which plagiarism can take form. The Spectrum makes these forms memorable by tagging the types with “Digital 2.0” monikers, a gesture that both acknowledges the role that the internet plays in instances of content copying and makes the types more meaningful for a generation of writers who are “digital natives.”1

As part of the Plagiarism Spectrum project, a May 2012 survey of nearly 900 secondary and higher education instructors was also conducted to assess the frequency with which these types appear as well as the degree to which each type is problematic for instructors.

Each of the 10 most common types of plagiarism are defined below. The types are ranked in order of severity of intent.
