Citing Sources in the Text of Your Paper
When you use an outside source, you must give credit to the original creator.
This allows your reader to easily connect your in-text citation with the full bibliographic entry.
Each style guide (MLA, APA, Chicago, ASA, Turabian) has its own rules for doing this.
