Committee on Publication Ethics

"The COPE flowcharts have been written and designed as
a practical step-by-step guide for journal editors to
deal with the most common breaches of publication
ethics that crop up repeatedly in scientific and
biomedical journals before and after publication.

The 14 flowcharts have been informed by the hundreds
of cases from around the world on which COPE has
advised since its foundation in 1997. These breaches
range from duplicate (redundant) publication through
to copying other researchers? work (plagiarism) to out
and out fraud."
