When should I use footnotes in MLA style?
In MLA style, footnotes or endnotes can be used to provide additional information that would interrupt the flow of your text.
This can be further examples or developments of ideas you only briefly discuss in the text. You can also use notes to provide additional sources or explain your citation practice.
You don’t have to use any notes at all; only use them to provide relevant information that complements your arguments or helps the reader to understand them.
