BibTeX, biblatex and biber ⇒ Warning about empty Bibliography

[WalidSaladin]

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.

Code: Select all

%Preamble begins
\documentclass[a4paper,12pt]{book}
\usepackage[utf8]{inputenc}
\usepackage{parskip} 
\usepackage{subscript}
\usepackage[margin=2cm]{geometry} 
\usepackage{caption}
\usepackage{graphicx}
%Preamble ends

\begin{document}
This is an example.

\bibliography{FirstLatexDoc_lib}
\bibliographystyle{plain} 
\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

Code: Select all

\nocite{*}

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

Thank you for explaining this to me, Stefan_K.
