Citations (or sometimes called references) are essential to creating bibliographies/reference lists, or footnotes, or in-text references. The University of Missouri Libraries provide a helpful webpage on the Anatomy of a Citation. Consult Citation Styles to learn about disciplinary-wide styles such as APA, MLA, Chicago, CSE, etc.
The Citation Management Tools webpage can help you determine which citation manager to use to organize and automatically format your bibliographies as well as store publication PDFs. For a more comprehensive overview, see Comparison of Reference Management Software.
