The section sign (§) (also known as the section marker, section symbol, paragraph sign, paragraph marker, paragraph symbol, double S or section mark or paragraph mark for short in parts of Europe) is a letter that is an alternate form of ß used in legal code. It is also a punctuation mark. This character is used to refer to a section in legal code. For example, in the APA style: "Title 16 of the United States Code Section 580p" becomes "16 US Code § 580p", which shows the section sign in place of "United States Code Section".
