No matter how many authors, always double-space everything and use a hanging indent (first line flush left, rest indented). Why? Because it looks sharp, like a well-tailored blazer for your bibliography. And if you forget the indent, your paper will look like a messy pile of laundry. You don’t want that.
So go ahead: cite your two, three, or seventeen authors. You’ve got this. And if all else fails, just remember: “et al.” is your best friend and commas are your frenemies. Now go treat yourself to actual coffee—you’ve earned it.
