[Tex/LaTex] Numbering appendices by letter instead of number

Question

I'm trying to get a hold of numbering the letter of the appendices. This is how it looks now:

\documentclass[11pt, a4paper, twoside]{article}

% PACKAGES
\usepackage{geometry}
\usepackage{lipsum}        

\begin{document}
\tableofcontents

\section{First section}
\subsection{A subsection}
\lipsum[1]

\appendix
\section{Appendices}
\subsection{First appendix}
\subsection{Second appendix}

\end{document}

But instead of counting the numbers

A.1
A.2
…

I want to the letters to be increased. It should be something like this:

Appendices
A – first appendix
B – second appendix
C – third appendix

where "Appendices" is a section, and the other are subsections.

I hope that anyone can help me 🙂

Answer 1

If you really need the appendices to be subsections you can change numbering of subsections using \renewcommand{\thesubsection}{\Alph{subsection}}:

\documentclass[11pt, a4paper, twoside]{article}
\usepackage{geometry}
\usepackage{lipsum}

\begin{document}
\tableofcontents

\section{First section}
\subsection{A subsection}
\lipsum[1]

\appendix
\section*{Appendices}
\addcontentsline{toc}{section}{Appendices}
\renewcommand{\thesubsection}{\Alph{subsection}}

\subsection{Appendix Subsection}
\subsection{Another appendix Subsection}
\end{document}
