"A summary, written in your own words, briefly restates the writer's main points. Paraphrase, although written in your own words, is used to relate the details or the progression of an idea in your source. Quotation, used sparingly, can lend credibility to your work or capture a memorable passage."
(L. Behrens, A Sequence for Academic Writing. Longman, 2009)
