IEEE Publications has long maintained the policy that verbatim copying of another's work (plagiarism) is unacceptable author conduct.
In November 2002, the IEEE Board of Directors approved a new policy on Duplicate Publication and Self-Plagiarism. This policy is found in the IEEE Policies document, Sections 6.4.1B(f) and 6.4.1B(h). These two sections are given below.
(f) Plagiarism is unacceptable. The verbatim copying or reuse of one's own research) as indicated in paragraph "h" below) is considered another form of plagiarism or self-plagiarism; it is unacceptable.
(h) Except as indicated in Section 6.3.4 (Multiple Publication of Original Technical Material in IEEE Periodicals), authors should only submit original work that has neither appeared elsewhere for publication, nor which is under review for another refereed publication. If authors have used their own previously published work(s) as a basis for a new submission, they are required to cite the previous work(s) and very briefly indicate how the new submission offers substantial novel contributions beyond those of the previously published work(s).
