Which command is used by bibtex to create the bibliography header?

I'm using multibib to create a list of articles in an appendix.

%Preamble...
%Create new macros for citation in "lit" group
\newcites{lit}{My list of articles}

%The appendix
\appendix
\chapter{My list of articles}
%Force use of citations
\nocitelit{ref01}
...
\nocitelit{refNN}
%Stop clear double page
\newcommand{\foo}{}
\let\cleardoublepage\foo
%Will print bib heading
\bibliographylit{myrefs}

The problems I ran into was that I wish to replace the automatic chapter heading generated by the \bibliographylit command (which in turn uses bibtex, I guess) with a NULL command so that I can use my own appendix chapter heading. I could remove the double page clearing by using the command:

\newcommand{\foo}{}
\let\cleardoublepage\foo

And I wish to do the same but with the whole chapter heading. Redefining \chapter left me with a * in the place of the chapter.

As suggested here: Bibliography as section in LaTeX / BibTeX this didn't wor开发者_如何学Gok: http://www.flakery.org/search/show/568 (\bibsection is undefined)

Ok, my understanding of \renewcommand was lacking. Adding two arguments as:

\renewcommand{\chapter}[2]{}

Everything works!

Edit: I've also learned that you can "scope" the redefintion, so to leave \chapter command untouched after this bibliography I do:

\chapter{Appendix with references}
{ %Disable chapter command
\renewcommand{\chapter}[2]{}
\bibliography{myrefs}
}

Pretty sweet!
