Self-plagiarism is typically defined as the recycling or reusing of one's own actual words from already published publications, and it is a serious offence. However, while it does not cross the line into outright stealing of other people's ideas, it can nonetheless cause problems in the field of scholarly publishing. Self-plagiarism can relate to the publishing of identical works in two different places (a practice known as "duplicate publication"), in addition to the use of verbatim chunks of text.
