Citing your sources is a way to introduce your reader to the conversations you've been having with others (through articles, books, media, etc.) about your topic. Disciplines use various citation styles as both a rhetorical strategy and a way to signal relative importance of certain aspects of the sources to the reader, among other reasons. For example, Modern Language Association (MLA) citation style emphasizes the names of authors, which is important in the fields of literature and literary analysis - critical forms of discourse in that discipline.
