# 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.
