TOC in double language

Question

For my thesis, I have to write the table of contents in two different languages.. (don't ask me why...). Is there a way to do it?

Answer 1

Since you changed the question, here is how to make an additional TOC in a different language.

1. Look how is \tableofcontents defined in your class. For example, in article.cls it is defined as

   \newcommand\tableofcontents{%
     \section*{\contentsname
       \@mkboth{%
         \MakeUppercase\contentsname}{\MakeUppercase\contentsname}}%
    \@starttoc{toc}%
    }
   

   So we can define a new table with filename file.tos and define it as

   \makeatletter
   \newcommand\spanishtableofcontents{%
     \selectlanguage{spanish}%
     \section*{\contentsname
       \@mkboth{%
         \MakeUppercase\contentsname}{\MakeUppercase\contentsname}}%
    \@starttoc{tos}%
     \selectlanguage{english}%
    }
    \makeatother
   

2. Now just add to your sectioning commands writing to the new table (it is possible to add this to the command itself, but since you need to translate the heading anyway, it might be simpler to do it manually):

   \section{Word}%
   \addcontentsline{tos}{section}{\protect\numberline{\thesection} Palabra}
   

   and similarly for subsections etc.

Answer 2

If you have an index in several languages then you mean that you have different index entries that sort differently. This can be easily achieved, for example with the index package. This package supports the generation of different indexes via the command \newindex and the entries then end up in different files.

Each of those files can then be sorted individually using, say makeindex.

Answer 3

I would do it in this way using multind package and babel:

\usepackage{multind}
\makeindex{spanish}
\makeindex{english}

...

The word\index{english}{Word}\index{spanish}{Palabra}

...

\selectlanguage{spanish}
\printindex{spanish}
\selectlanguage{english}
\printindex{english}
