The document provides examples of both correct and incorrect ways to cite sources and avoid plagiarism when using direct quotes or paraphrasing the ideas of others. It uses a quote from a J.K. Rowling commencement speech as the original source material and examples attributed to characters from the Harry Potter series to demonstrate plagiarized, questionable, or properly cited summaries of the quote. Hermione Granger's example shows the correct format of using in-text citations and quotation marks around the original wording.
