Maina S, Di Napoli M. Duplicate publication and plagiarism: is RHC safe? Reviews in Health Care 2012;3(4):225-227
While plagiarism obviously represents scientific misconduct, the so-called "self-plagiarism", or duplicate publication, is more controversial. It can include: same study sample, control data, or study outcomes; the so-called "salami slicing" (a large study sliced into several smaller studies); multiple submission; and republication in another language. Some authors are not aware of copyright rules, nor of publication ethics. Reviewers and editors have certainly an essential role in detecting any scientific misconduct and avoiding plagiarism and duplicate publication. Cooperation between editors and authors, and transparency are needed, too.
