The document provides guidance on citing sources in research writing. It explains that sources should be cited to establish credibility, build on previous scholarship, and give proper credit. Direct quotations, others' ideas, statistics, and images all require citation. Common knowledge or one's own ideas and conclusions do not. The document also demonstrates how to paraphrase others' work, including integrating the paraphrase into one's own writing with a topic sentence, transition, and conclusion. In-text citations are paired with a full citation in a works cited list.
