# Appendix Section Title

I am writing a paper in the "article" document class.

When it proceeds to my appendix, I would like the two sections to have titles to appear as "Appendix A. Some notation" and "Appendix B. Some more notation". So I trited

\appendix
\section{Some notation}
\section{Some more notation}


However, I got "A Some notation" and "B Some more notation" as titles. How can I fix this problem?

• Please edit your post to provide a complete, small document people can copy-paste-compile. That is a lot more useful than a mere fragment. In what way didn't they work well? What specifically did you try? – cfr Feb 4 '15 at 13:42

The title option and the appendices environment of the appendix package can do that:

\documentclass{article}

\usepackage[title]{appendix}

\begin{document}

\section{title 1}
\section{title 2}

\begin{appendices}
\section{Some Notation}

\section{Some More Notation}
\end{appendices}

\end{document}


• what if I want a period (as OP)? [Appendix A. Some notation] instead of [Appendix A Some notation]? – Seub Oct 16 at 23:37
• You can add this, just after begin{appendices}: \makeatletter \def\@seccntformat{\appendixname\ % \csname thesection\endcsname. \quad} \makeatother. – Bernard Oct 17 at 0:49
• Sorry, can you clarify, maybe in your answer or something? It doesn't quite work when I paste, I must do something wrong. Should there be a % there? – Seub Oct 17 at 2:40
• @Seub: Indeed, in my code there is a % at the end of the line (to prevent some spurious space or any other side effects), and I didn't notice that in comments, line breaks disappeared. – Bernard Oct 17 at 9:43
