A citation is a reference to a book, article, video, website, or other information source for the purpose of giving credit to the author. Citations also give your work more credibility because your readers can find out exactly where you got your information. Citations typically include: author names, title, publisher, publisher location, date of publication, journal title, volume, issue, and/or page numbers. Citing your sources is a fundamental research skill.
