The document provides guidance on how to cite sources in MLA style. It explains that sources must be cited in two cases: when using direct quotes or when paraphrasing ideas from a source. For both cases, the author's name and other identifying information should be included in parentheses after the quote or paraphrased text. The specifics of what information to include, such as page numbers, depends on whether the source is a book, website, or other media. Examples are provided for different source types. Maintaining accurate citations and a works cited list is important to avoid plagiarism.
