HELP AN :XMAS: OUT Options

[batman]

have you ever had to write an essay with extensive footnotes?

my professor for my art humanities class basically said "make sure you add a lot of footnotes!" without elaborating on what exactly she wants in the footnotes. i'm not exactly sure how i should go about doing this.

all the "how to write footnotes" websites i look at tell me it's pretty much just an in-text citation with the reference at the bottom of each page, but all the art articles i read usually include some type of brief description or blurb about the article/reference/etc in their footnotes.

do u know 'bout dis?
