Plagiarism is appropriation of someone else’s ideas, texts, images and other materials without acknowledging their author. It is a serious violation of publication ethics that once detected results in the retraction of the submitted article. It has a disastrous impact on the author’s reputation, because the publication is not removed from online databases, but stored there with a retracted publication tag. Plagiarism comes in different forms many of which still cannot be detected even by a special software; Plagiarism comes in different forms; the originality of an article is still assessed by peer reviewers and readers in the first place. Plagiarism can be unintentional. Most often, poor citation and reference style is typical of young researchers. To avoid unpleasant situations, authors are advised to use paraphrasing instead of merely copying and pasting fragments of texts. A verbatim use of a source requires quotation marks, references are expected to come right after the fragment borrowed from the original source; with multiple references (from 5 to10) pointing to a single idea are bad style. Authors are advised to always double check basic information about the publication they specify in a reference.
