Each discipline has a preferred citation style for researchers, and understanding how to select the right style is important. Published works need to conform to accepted standards within disciplines, and a citation style provides a uniform way to document the sources used in the preparation of the work.
A citation manager will help you create, edit, and organize citations for your sources. These tools, such as Zotero and Mendeley, will even create bibliographies and in-text citations for you as you write your paper.
