When a citation is not needed

Common sense and ethics should determine your need for documenting sources. You do not need to give sources for familiar proverbs, well-known quotations or common knowledge. Remember, this is a rhetorical choice, based on audience. If you’re writing for an expert audience of a scholarly journal, for example, they’ll have different expectations of what constitutes common knowledge.
