When using someone else’s work, you must indicate you have borrowed the idea by giving a citation. Besides, if a source’s exact words have to be copied, quotation marks must be given. However, verbatim copy of large sections of text (including a few sentences, whole paragraph, and several paragraphs) is moderate to most severe type of plagiarism whether or not that work is cited or quotation marks are used, even though the original sources are from author’s own publications.
