Plagiarism at arXiv, and Nature journals' policies
This week's Nature (449, 8; 2007) features a News story about a plaigiarism scandal involving more than a dozen theoretical physicists at four universities in Turkey. Almost 70 papers by 15 authors have been removed from the popular preprint server arXiv, where many physicists post their work, by the server's moderators. They allege that the papers plagiarize the works of others or contain inappropriate levels of overlap with earlier articles. This is probably the largest single incident of its sort ever seen on the server, according to physicist Paul Ginsparg of Cornell University in Ithaca, New York, and founder of arXiv. "What these guys did was way over the line," he says. See here for the full version of the story (site licence or subscription required).
According to the Nature News story, Ginsparg says that it's not uncommon for scientists with a poor command of English to plagiarize introductions or background paragraphs from earlier work, often adding an appropriate citation. He thinks that although such practices are ethically questionable, it is inappropriate to be overly draconian. A recent analysis turned up numerous examples of plagiarism on the arXiv server (see Nature 444, 524–525; 2006).
The Nature journals' policies on plagiarism can be found on our free-access author and referees' website. The policy page contains links to various (free access) Editorials written in the Nature journals on the topic which, taken together, we hope provide a useful guide for authors.
