Plagiarism is the use or close imitation of another author's language and ideas and representation of them as one's own original work. Duplicate publication, sometimes called self-plagiarism, occurs when an author reuses significant parts of his or her own published work without providing appropriate references. This can range from getting identical papers published in multiple journals, where the author adds a small amount of new data to an earlier paper.

Editors will assess each case to which they are aware (either on their own knowledge and reading of the literature, or when alerted by the referee) on their own merits. If a case of plagiarism is uncovered after the paper has been published in the IVRJ Journal, the journal will conduct a preliminary investigation. If plagiarism is found, the journal will contact the author or institution. A violation determination will direct the Journal to execute a statement, connected two-way online to and from the original paper, to record plagiarism and provide references to plagiarized material. IVRJ only considers manuscripts that contain less than 20% plagiarism. If any manuscript contains more than the stated percentage, it will be returned to the author for plagiarism removal. If the author does not submit a revised manuscript with less than 20% plagiarism, IVRJ will reject the manuscript.
