No matter which citation style you use, there will be two levels of citation required. Citations within the text of the document(usually indicated parenthetically or as footnotes) and citations at the end of the text( Works Cited, References, Bibliography, etc.). Both levels are required and both will be formatted differently. Citations within the text are usually short and point the reader to the full citation at the end of the text.
Level One Example:
In-Text:

Level Two Example:
