Bibtex “didn't find a database entry”

manpreet Best Answer 2 years ago

I'm having issues creating citations in my document. My text file states:

\documentclass[11pt]{article}

\usepackage[round]{natbib}

\begin{document}

Their long-term aid \citet{Haggarty:01}

\bibliographystyle{plainnat}
\bibliography{Quotes}

\end{document}

My bibtex file is:

\begin{thebibliography}

\bibitem[Haggarty and Pepin(2001)]{Haggarty:01}
L. Haggarty and B. Pepin.
\newblock An Investigation of Mathematics Textbooks and their use in English, French and German Classrooms.
\newblock \emph{Proceedings of the British Society for Research into Learning Mathematics}, 21\penalty0 (2):\penalty0 117--125, 2001.

\end{thebibliography}

When I latex, bibtex, latex, latex I get the following warning:

Warning--I didn't find a database entry for "Haggarty:01"

I've creating references like this before a long time ago, so I can't remember if there's anything else I should be doing. I've tried deleting the .aux file before running a fresh but nothing seems to help. Where am I going wrong?
