What is self-plagiarism?

Self-plagiarism, also known as recycling fraud, occurs when an author reuses text in subsequent writings without attributing the previous publication.1, 2, 3

Is self-plagiarism ever acceptable?

Thomas Jefferson repeated prose from previous writings in the Declaration of Independence and did not cite these works.4 Few would argue this famous example of self-plagiarism as unacceptable.

Most also agree that experts providing opinions to popular newspapers or magazines need not cite specific previous writings.

What is copyright?

The US Constitution grants Congress the power to “promote the progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.” Copyright is this legal protection of a particular expression of an idea, but not of the facts or ideas themselves.5 In the United States, copyright protection extends for the life of the author plus 70 years.6

How does self-plagiarism involve copyright infringement?

Authors of technical articles are often asked to assign copyright to a journal's owner or publisher as a condition for publication—such is the case for the Journal of the American Academy of Dermatoloy, whose owner is the American Academy of Dermatology. In many cases, the publisher handles permission requests from authors. Elsevier does this for the Journal. Subsequent republication by the author of copyrighted text without permission and citation is technically illegal—but permission is

Have authors been legally sanctioned for violating copyright on their own words?

Few sanctions have been handed down, because the courts have generally recognized that “authors have special rights to their words not withstanding copyright.”3

If copyright law has not been enforced against authors repeating themselves, then why worry about self-plagiarism?

Self-plagiarism is not acceptable in academic writing because academic writing is grounded by its references, and authors are expected to cite their closely related previous writing.

    Ethical breaches of publication and scientific integrity exist including: data manipulation and falsification, duplicate manuscripts, redundant publication, plagiarism (print and electronic), human or animal use concerns, and author conflicts of interest with failure to disclose.32,33 Self-plagiarism occurs when authors recycle their own previous work without full disclosure to the original publication.34,35 This occurs in the form of redundant and dual publication, copyright violation, and “salami publishing.”
