Hi Ian,

Thanks for the reply. The part which I'm tripping over is:

#+latex: \chapterauthor{by Mike Anderson}
(add-to-list 'org-latex-classes
          '("koma-book"
             "\\documentclass{scrbook}"
             ("\\chapter{%s}" . "\\chapter{%s}")
             ("\\subsection{%s}" . "\\subsection*{%s}")
             ("\\subsection{%s}" . "\\subsection*{%s}")
             ("\\paragraph{%s}" . "\\paragraph*{%s}")
             )
     )

Where should I add this definition?

My setup is:

Main.tex
writeup.tex


Writeup.tex is suppsed to have all the chapters without preamble. Main.tex has the preamble, abstract, \input{writeup}, and bibliography.

Thanks,
Rishabh

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
           '("koma-book"
              "\\documentclass{scrbook}"
              ("\\chapter{%s}" . "\\chapter{%s}")
              ("\\subsection{%s}" . "\\subsection*{%s}")
              ("\\subsection{%s}" . "\\subsection*{%s}")
              ("\\paragraph{%s}" . "\\paragraph*{%s}")
              )
)


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.
