How to change the name of document elements like “Figure”, “Contents”, “Bibliography” etc.?

Question

I'd like to modify the names used to typeset some of my document elements. For example, the caption of figure floats should change from "Figure" to "Fig.", and my \tableofcontents sectioning heading shouldn't read "Contents", but "Table of Contents". How can I do that?

\documentclass{article}
% \usepackage[english]{babel}
\begin{document}
\tableofcontents
\section{foo}
\begin{figure}[h]
\centering
\rule{1cm}{1cm}% placeholder for graphic
\caption{A figure}
\end{figure}
\end{document}

Answer 1

The answer depends on whether or not you use the babel package.

Without babel

Names like "Figure" and "Contents" are stored in macros like \figurename and \contentsname, i.e., to change them, you have to change the definition of the respective macros. Add the following to your preamble:

\renewcommand{\figurename}{Fig.}
\renewcommand{\contentsname}{Table of Contents}

Here's a list of the "name macros" (and their default meaning) defined by the LaTeX standard classes article, book, and report:

• \abstractname [only article, report]: Abstract
• \appendixname: Appendix
• \bibname [only book, report]: Bibliography
• \chaptername [only book, report]: Chapter
• \contentsname: Contents
• \figurename: Figure
• \indexname: Index
• \listfigurename: List of Figures
• \listtablename: List of Tables
• \partname: Part
• \refname [only article]: References
• \tablename: Table

Other classes and packages may define additional "name macros"; here are some you're likely to come up against (plus their source):

• \acronymname [glossaries]: Acronyms
• \alsoname [makeidx]: see also
• \ccname [letter]: cc
• \enclname [letter]: encl
• \glossaryname [glossaries]: Glossary
• \headtoname [letter]: To
• \lstlistingname [listings]: Listing (the environment)
• \lstlistlistingname [listings]: Listings (the "List of")
• \nomname [nomencl]: Nomenclature
• \notesname [endnotes]: Notes
• \pagename [letter]: Page
• \prefacename [babel]: Preface
• \proofname [amsthm]: Proof
• \seename [makeidx]: see (misdefined as "see also" in the AMS classes)
• \seeonlyname [AMS classes]: see

With babel

The same principles as above apply – with one crucial difference: for every language, "name macros" must be redefined in the argument of \addto\captions<language> (instead of a simple \renewcommand). That is, for the English language, you'd have to add the following to your preamble (after loading babel):

\addto\captionsenglish{%
  \renewcommand{\figurename}{Fig.}%
  \renewcommand{\contentsname}{Table of Contents}%
}

Changing "Bibliography" and "References" with biblatex

The biblatex package is an exception to the rule: It uses "bibliography strings" for (among other things) the headings of bibliographies, so redefining \bibname or \refname won't work (whether you use babel or not). To rename both "Bibliography" and "References" to "Works Cited" for the English language, add the following to your preamble:

\DefineBibliographyStrings{english}{%
  bibliography = {Works Cited},
  references = {Works Cited},
}

Afterword

"Name macros" should only contain the string to be printed. Don't add formatting instructions like \renewcommand{\contentsname}{\vspace{20pt}{\Huge Table of Contents}} – they may "work" in the document body, but are likely to play havoc with, e.g., headers and bookmarks. To change the formatting of the "Contents" heading, either redefine \tableofcontents as shown in this answer or, if you want your changes to apply to all sectioning headings, have a look at the titlesec package. For captions, the caption package offers a host of customization possibilities.

In addition to the answer of lockstep:

With KOMA-Script

KOMA-Script (to be correct, package scrbase, which is called in the KOMA-Script classes scrartcl, scrreprt, scrbook and scrlttr2 and in the KOMA-Script package scrextend) defines two macros for naming or renaming LaTeX names:

\newcaptionname{language}{LaTeX name}{new content}
\renewcaptionname{language}{LaTeX name}{new content}

Here is a example for German language:

\renewcaptionname{ngerman}{\contentsname}{Inhalt}           %Table of contents
\renewcaptionname{ngerman}{\listfigurename}{Abbildungen}    %Figures
\renewcaptionname{ngerman}{\listtablename}{Tabellen}        %Tables
\renewcaptionname{ngerman}{\figurename}{Abb.}               %Figure
\renewcaptionname{ngerman}{\tablename}{Tab.}                %Table
\renewcaptionname{ngerman}{\bibname}{Literatur}             %Bibliography
  \newcaptionname{ngerman}{\lstlistlistingname}{Quelltexte} %Table of listings 
  \newcaptionname{ngerman}{\lstlistingname}{Quelltext}      %Listing

You can see, that \renewcaptionname renames an existing LaTeX name like \contentsname. The macro \newcaptionname defines a new LaTeX name for KOMA-Script like \lstlistingname.

If you use package babel together with KOMA-Script it is better to use the mechanism of KOMA-Script instead of babels because KOMA-Script has a better verification.

Update:

With loading the package scrextend (see chapter 16, file scrguien.pdf, texdoc scrguien) you can use some KOMA-Script features with non KOMA-Script classes. For example scrextend loads scrbase.

The following MWE shows, that it works nice, and that loading of scrextend does not redefine the default font for titles in standard classes: it stays in serif (roman), while in KOMA-Script the default is sans-serif. Compile first with the commented line, then uncomment and compile again. Compare the titles of the table of contents.

\listfiles                  % to check if scrbase is loaded
\documentclass{article}     % original class
\usepackage{scrextend}      % allows some KOMA-Script features
\usepackage[english]{babel} % needed for "blindtext"
\usepackage{blindtext}      % to create dummy text

% \renewcaptionname{english}{\contentsname}{Contents of ``Blindtext''} % renaming in KOMA-Script

\begin{document}
\tableofcontents
\newpage
\blinddocument             % dummy text including several headings for TOC 
\end{document}

Update 2:

If you are not sure whether package scrbase is loaded or not you can test it with the command \listfiles (see first line in the MWE above). Command \listfiles prints in the log file a list with all called packages in your document. So if package scrbase is loaded you find it in this list (including used version), like this:

scrkbase.sty    2012/07/29 v3.11b KOMA-Script package (KOMA-Script-dependent basics and keyval usage)
 scrbase.sty    2012/07/29 v3.11b KOMA-Script package (KOMA-Script-independent basics and keyval usage)

For documents using minted package by Konrad Rudolph, one can change the name of document elements as follows:

\renewcommand\listingscaption{Code-Snippet}
\renewcommand\listoflistingscaption{List of program codes}
