Duplicate publication

Duplicate publication, multiple publication, redundant publication or self-plagiarism refers to publishing the same intellectual material more than once, by the author or publisher. It does not refer to the unauthorized republication by someone else, which constitutes plagiarism, copyright violation, or both. Multiple publication of the same research can also skew meta-analyses and surveys.
