# Index both authors and subjects with authorindex and makeindex

I am trying to make two separate indexes for my PhD dissertation, the author index and the subject index. Creating the author index is quit easy, I just use the \usepackage{makeidx} and \printindex command and LaTeX creates a beautiful author index for me. What if I want to add the subject index before the author index? I have read the responses to the similar question on StackExchange: How can I have two or more distinct indexes? but it is not a viable solution for me, because it requires me to manually index both authors and subjects. Currently, I do not have to index the authors and latex creates the index for me automatically. Is there any way to only index the subjects manually ( I mean to use \index{key} for every subject of interest) and have the authors index automatically? The \authorindex package does not work with \natbib

• Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}.

• With author index you mean the bibliography?

• How should LaTeX know that a specific Word is an author? You will need to tag them somehow if you want a real index and not just a bibliography. What you can do (using the linked answer) is to create a command, e.g. \authorindex{} that encapsules the \index{authors}{Author} line. Apr 30 '14 at 4:20
• No, with author index I mean a list of authors and the page numbers which they have been cited in. It is completely different from the bibliography. Apr 30 '14 at 4:37
• The nice thing about \authorindex package is that I do not have to index the authors manually! It creates the author index automatically. please see here for an example: tex.stackexchange.com/questions/24332/… Apr 30 '14 at 4:40

The authorindex and natbib packages collide at first glance, but in section 7.2.3 of the manual (http://mirrors.ctan.org/indexing/authorindex/authorindex.pdf) a solution is provided by using a local natbib.cfg, which I just copy from the manual, I have not developed that material:

Content of natbib.cfg:

\AtBeginDocument{%
\ifNAT@numbers
\let\org@@citex\NAT@citexnum
\else
\let\org@@citex\NAT@citex
\fi
\def\@citex[#1][#2]#3{%
\typeout{indexing: [#1][#2]{#3}}%
\org@@citex[#1][#2]{#3}%
\@aicitey{#3}}%
\renewcommand\NAT@wrout[5]{%
\if@filesw{%
\let\protect\noexpand\let~\relax
\immediate\write\@auxout{\string\aibibcite{#5}{#1}}%
\immediate\write\@auxout{\string\bibcite{#5}{{#1}{#2}{{#3}}{{#4}}}}}%
\fi}}{}}
\endinput


Place this file (exactly with this name!) in the folder where your document source is stored.

The next step is to replace all \aicite commands with 'traditional' \cite (otherwise it does not work. Why???? I have no clue, but I did not look into the package files either)

I added the rather simple command \listofauthors, which includes the authorindex, further formatting is not done, however.

\documentclass[12pt]{book}

\usepackage{natbib}
\usepackage{blindtext}

\usepackage{makeidx}
\usepackage[pdftex,plainpages=false]{hyperref}
\RequirePackage{authorindex}

% Use this, if you want hyperlinks back from list of author entry to page
% where the citation was placed
\def\theaipage{\string\hyperpage{\thepage}}

\newcommand{\listofauthorsname}{List of Authors}%

\newcommand{\listofauthors}{%
\chapter*{\listofauthorsname}%
\phantomsection%
\noindent%
\printauthorindex%
}%

\makeindex
\begin{document}

\tableofcontents

\chapter{Introduction}

Einstein showed that  $E = m \cdot c^2,$
i.e. the equivalence\index{Equivalence} of mass\index{Mass} and energy\index{Energy}.\par

In their books \cite{GSM97} or \cite{Lam94} show how to typeset those equation ;-)

\blindtext

\printindex

\bibliographystyle{alpha}
\bibliography{biblio}

\listofauthors

\end{document}


Workflow on foo.tex

1. pdflatex foo.tex
2. makeindex foo
3. bibtex foo
4. authorindex foo
5. pdflatex foo

• You can use of of the existing bib files in your tex distribution. They are under \$TEXMF/bibtex/bib/

• @Christian: Thank you very much for the useful help. What if I want to use the \natbib package? When I do so, right after the \begig{document} I use \citeindextrue and the index of authors will appear with \printindex but \printauthorindex does not work! here it says that I have to use perl. tex.loria.fr/bibdex/authorindex.pdf what is your idea?

• @ChristianHupfer again to clarify, with \natbib package, \printauthorindex is not producing anything. to get the index of authors, I should use \citeindexture and \printindex together. the problem is that in doing so, the index of authors and subjects get mixed together! Apr 30 '14 at 13:30
• @user50822: I'll look after later on.
