A citation gathers all the identifying information about a source you used so that it can be identified and found by your reader. When you cite the work you use on a works cited page, your project becomes trustworthy. If you create a project using sources and don't cite your sources in a works cited page, you are passing off other people's work as your own. That is plagiarism, and you are plagiarizing.
The information in a citation can include:
