How to Add an Appendix with Separate Numbering in LaTeX
Appendices in LaTeX switch to letter-based numbering (Appendix A, B, C) with sections numbered A.1, A.2, etc. The \appendix command handles this automatically.
Basic Appendix
The \appendix command switches chapter/section numbering to letters:
\begin{document}
% Main content
\chapter{Introduction}
...
\chapter{Conclusion}
...
% Switch to appendix numbering
\appendix
\chapter{Supplementary Proofs}
\label{app:proofs}
Here we present detailed proofs...
\section{Proof of Theorem 1}
% This becomes Section A.1
...
\chapter{Additional Data}
% This becomes Appendix B
...
\end{document}Using the appendix Package for More Control
The appendix package gives you finer control over appendix formatting:
\usepackage[toc,page]{appendix}
\begin{document}
% ... main content ...
\begin{appendices}
\chapter{Derivations}
Detailed derivations for Chapter 3.
\chapter{Survey Questions}
The full survey instrument.
\end{appendices}
\end{document}
% 'toc' adds "Appendices" header in table of contents
% 'page' adds a separate "Appendices" page💡 Tips
- •Use \appendix before your first appendix chapter — it changes numbering from that point on
- •Reference appendices normally: \ref{app:proofs} produces 'A'
- •The appendix package's [toc] option adds a clear separator in the table of contents
- •For articles, \appendix changes \section numbering to A, B, C
