Warning about empty Bibliography

Postby WalidSaladin » Wed Mar 06, 2013 1:01 pm

How do I address this warning?

LaTeX warning:Empty `thebibliography' environment on input line 3.

Here is a simplified version of my code. The preamble contains all the packages I have loaded so far. I attached the BibTex document.

  1. %Preamble begins
  2. \documentclass[a4paper,12pt]{book}
  3. \usepackage[utf8]{inputenc}
  4. \usepackage{parskip}
  5. \usepackage{subscript}
  6. \usepackage[margin=2cm]{geometry}
  7. \usepackage{caption}
  8. \usepackage{graphicx}
  9. %Preamble ends
  11. \begin{document}
  12. This is an example.
  14. \bibliography{FirstLatexDoc_lib}
  15. \bibliographystyle{plain}
  16. \end{document}

Very good minimal example. You just don't need to include unrelated packages, better omit them even if you normally load them.

You need to cite a reference, or use \nocite, to let references appear in the bibliography. For example, to print the whole bibliography, add

  1. \nocite{*}

Otherwise only cited references appear. In this case, there are none, so the bibliography environment was empty.
