My professor said "2) Be sure to footnote your writing when necessary. Of course you do not have to footnote general information, and the difference is not always to see! If you're in doubt, footnote a whole paragraph, or even one sentence.

By the way, you may use endnotes OR footnotes, whichever you prefer."

But, i'm used to doing only in-text citations with a Works Cited at the end. Do I have to use end/footnotes if I am doing in-text citations with signal words?

Please help.

My professor told that I can pick what to use. If you are doing in-text citations then you don't need footnotes and vice versa.
