Plagiarism
Contested definition

Miguel Roig has written at length about the topic of self-plagiarism and his definition of self-plagiarism as using previously disseminated work is widely accepted among scholars of the topic. However, the term "self-plagiarism" has been challenged as being self-contradictory, an oxymoron, and on other grounds.

For example, Stephanie J. Bird argues that self-plagiarism is a misnomer, since by definition plagiarism concerns the use of others' material. Bird identifies the ethical issues of "self-plagiarism" as those of "dual or redundant publication". She also notes that in an educational context, "self-plagiarism" refers to the case of a student who resubmits "the same essay for credit in two different courses." As David B. Resnik clarifies, "Self-plagiarism involves dishonesty but not intellectual theft."

According to Patrick M. Scanlon, "self-plagiarism" is a term with some specialized currency. Most prominently, it is used in discussions of research and publishing integrity in biomedicine, where heavy publish-or-perish demands have led to a rash of duplicate and "salami-slicing" publication, the reporting of a single study's results in " least publishable units " within multiple articles (Blancett, Flanagin, & Young, 1995; Jefferson, 1998; Kassirer & Angell, 1995; Lowe, 2003; McCarthy, 1993; Schein & Paladugu, 2001; Wheeler, 1989). Roig (2002) has offered a useful classification system including four types of self-plagiarism: duplicate publication of an article in more than one journal; partitioning of one study into multiple publications, often called salami-slicing; text recycling; and copyright infringement.
