# What's the text command for this symbol?

Does anyone know the name of the symbol to the left ? I saw it as a way of numbering sections inside the book Basic Mathematics by Serge Lang.

• For future reference, Detexify can provide names of symbols that you draw by hand. – Sandy G May 18 at 22:59

Wikipedia calls it Section sign. \S does it

\documentclass[11]{article}
\begin{document}
\S
\end{document}


• Or simply § directly from the keyboard since nowadays, the default input encoding is utf8. – Bernard May 16 at 22:44
• \textsection should work also – Fab2 May 16 at 22:51

It is possibile, as alternative, to use \textsection in text-mode (as by comment of @Fab2) and \mathsection in math-mode.

\documentclass[a4paper,12pt]{article}
\usepackage{amsmath}
\usepackage{bm}
\begin{document}
\textbf{\textsection 5} or $\bm{\mathsection 5}$
\end{document}
