The section sign (§, Unicode
U+00A7, HTML entity
§) is a typographical character used mainly to refer to a particular section of a document, such as a legal code. It is also called "double S", "sectional symbol", "the legal doughnut", signum sectiōnis.
It is frequently used along with the pilcrow (¶), or paragraph sign. When duplicated, as §§, it is read as the plural "sections" (§§ 13–21), much as "pp." (pages) is the plural of "p." (short for the Latin pagina). The likely origin of the section sign is the digraph formed by the combination of two S'es (from the Latin signum sectionis).
Like the dagger (†) and double dagger (‡), it is also sometimes used to link to a footnote where the asterisk (*) is already in use on a given page; however, these usages are declining in favor of numbered footnotes, usually linked by a superscripted and/or square bracketed number.

In popular culture 
A modified version of the section sign is used in the Maxis games SimCity 3 and later and The Sims series, as the symbol of the in-game currency, the simoleon. The symbol is used like the $ sign to denote the US dollar.
The sections symbol is used to denote chapters and sections in David Foster Wallace's novel The Pale King, left unfinished with his death in 2008, which deals heavily with the labor and lives of American IRS workers.
The section symbol is used in the 2012 computer game XCOM: Enemy Unknown as a nationality-neutral currency symbol.
