&gt; Hi Everyone,
&gt; 
&gt; My question is about using Org-mode Export to Latex, but starting with
&gt; Chapter, then Section, and so on.
&gt; 
&gt; I found a solution on Stackexchange [1] but when I add that code to my
&gt; init file, restart emacs, and add &quot;#+LaTeX_CLASS: book_noparts&quot; to my
&gt; org file,  it apparently doesn't get read. The exported .tex is an
&gt; itemized list.
&gt; 
&gt; Any help with what I'm doing wrong would be great help. Also, if
&gt; there's a better way to make custom class files within the org-file
&gt; I'm working on, please do let me know.
&gt; 
&gt; Thanks,
&gt; RJ

Here is my setup using the koma-book class. This uses H1 as the chapter 
title. A typical chapter starts with:

** The Clubroom Project
#+latex: \chapterauthor{by Mike Anderson}


(add-to-list 'org-latex-classes
           '(&quot;koma-book&quot;
              &quot;\\documentclass{scrbook}&quot;
              (&quot;\\chapter{%s}&quot; . &quot;\\chapter{%s}&quot;)
              (&quot;\\subsection{%s}&quot; . &quot;\\subsection*{%s}&quot;)
              (&quot;\\subsection{%s}&quot; . &quot;\\subsection*{%s}&quot;)
              (&quot;\\paragraph{%s}&quot; . &quot;\\paragraph*{%s}&quot;)
              )
)


In the file to be exported:

#+latex_class: koma-book
#+LATEX_CLASS_OPTIONS: [a5paper,openany,font 10pt]
#+latex_header: \makeatletter
#+latex_header: \newcommand{\chapterauthor}[1]{%
#+latex_header:   {\parindent0pt\vspace*{-5pt}%
#+latex_header:   \linespread{1.1}\large\scshape#1%
#+latex_header:   \par\nobreak\vspace*{35pt}}
#+latex_header:   \@afterheading%
#+latex_header: }
#+latex_header: \makeatother
#+latex_header: \graphicspath{{../../images/}}
#+latex_header: \usepackage{hyperref}
#+latex_header: \usepackage{pdfpages}
#+latex_header: \hypersetup{
#+latex_header:     colorlinks,
#+latex_header:     citecolor=black,
#+latex_header:     filecolor=black,
#+latex_header:     linkcolor=blue,
#+latex_header:     urlcolor=black
#+latex_header: }
#+latex_header: \KOMAoptions{twoside=false}
#+latex_header: \usepackage{adjustbox}

The first chapter has:

#+latex: 
\includepdf{/home/ian/Documents/emacs/thecastle/images/frontcover.pdf}
#+latex: \setcounter{tocdepth}{2}
#+latex: \tableofcontents

This sets the TOC depthand adds the TOC at the start of the first 
chapter.

Hope that helps.

Ian.
