A few years ago launched the project of initiative group of citizens Dissernet, the purpose of which was to identify the authors of the theses, illegally using other people's results. Gradually, into the sphere of the project Dissernet were involved the Russian scientific journals. Dissernet project began to apply methods of analysis of arrays of texts, implemented in programs such as anti-Plagiarism, to research articles, published in journals. On the website of the project log directory, which, in the opinion of the Dissernet's experts, are showing signs of incorrect editorial policy. Experts negatively evaluate the use of text fragments from previously written articles. Such a case called plagiarism. Re-publication of the article also recognized as unethical act. Limit these ethical standards of Dissernet the author's right to create derivative works? According to the Civil code of the Russian Federation, the creation of derivative works is one of the ways to realize the exclusive right of the author to the work. The civil code does not regulate specific permissible methods and volumes of processing of a scientific work. The feasibility of creating a derivative work is entirely within the competence and responsibility of the author. The discussion in the scientific community on whether it is ethical to publish an article in several journals makes no sense. The ethical sphere can only include the obligation of the author to inform the publisher about the held or planned publication of the article in another journal. The Civil code of the Russian Federation establishes the mechanism of simple (non-exclusive) licenses: any publisher can obtain from the copyright holder a simple license to publish the article, including without its processing. Publication of an article in several journals is one of the ways enshrined in the law to realize the right of the author (copyright holder) to publicize the work.
