Making the bibliography appear in the table of contents

As Herbert has hinted, your document class may include options to control the inclusion of the bibliography in the table of contents. For standard classes (article, book, report), adding \usepackage[nottoc,numbib]{tocbibind} to your document preamble should work. See the tocbibind documentation for more details.

EDIT: Herbert's suggestion (adding \addcontentsline{toc}{section}{References}) may result in an incorrect ToC entry unless the Reference section is forced on a separate page with \clearpage:

\documentclass[11pt]{article}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
\end{filecontents}

\usepackage{blindtext}

\begin{document}

\nocite{*}

\tableofcontents

\section{foo}

\blindtext[3]

% \clearpage

\addcontentsline{toc}{section}{References}
\bibliographystyle{plain}
\bibliography{\jobname}

\end{document}

Using hyperref, one should say:

\cleardoublepage

\phantomsection

\addcontentsline{toc}{chapter}{Bibliography}

\bibliography{your_bib_archive}

The following should help, I think:

\documentclass[bibliography=totocnumbered]{scrartcl}

If you don't want the bibliography to have a chapter number, use the following instead:

\documentclass[bibliography=totoc]{scrartcl}
