# Bibliography preamble \bibpreamble natbib

I am trying to produce some text after the "References" heading, but before the numbered references themselves. I had read that using the natbib package and the command `\bibpreamble{...insert preamble here...}` should do just that, however, I cannot get this to work.

My (abridged) code is as follows:

``````\bibliographystyle{plainnat}
\bibliography{library}
\bibpreamble{\ \\
For an in-depth discussion on... see
\cite{Baikie1988}, and for ... see
\cite{Cardona1978, Ley1979}.}
``````

This produces the References heading, the numbered references then this block of text at the end. Placing it before the `\bibliographystyle{}` command makes this block of text appear before the References heading. It is as if the command `\bibpreamble{}` is not being recognised by LaTeX.

``````\renewcommand{\bibpreamble}{<text of the preamble>}
The content of `\bibpreamble` is printed by the command producing the bibliography, thus it should be defined before issuing the command for the bibliography.
