Reusing substantial portions of one's own previously published work in a new publication without disclosure or appropriate citation. A reuse qualifies if a reader is led to believe the material is new when it is not.

Editorial commentary

Self-plagiarism, sometimes called text recycling, sits on a spectrum: trivial reuse of methods boilerplate is widely tolerated and even encouraged; substantial reuse of results, discussion, or conclusions across articles is not. The Text Recycling Research Project (Cary Moskovitz et al.) has produced practical guidance distinguishing 'developmental' from 'duplicate' recycling. Editorial responses depend on whether the reuse was disclosed at submission.
