Bibliography is not plotting

Question

So I'm using a template I've found on latextemplates.com and I'm trying to print the bibliography but nothing seems to be working. Also no error warning appears, it just simply skips it.

\usepackage[backend=biber,style=authoryear,natbib=true]{biblatex} 
\addbibresource{library.bib} 
\begin{document}
  some text bla bla bla
\printbibliography[heading=bibintoc]
\end{document}

I've changed the backend to every one I've found online: bibtex, biber and bibtex8.

And it seems that every time I compile it creates a *.bib file automatically.

What can I do?

Answer 1

I have used one of my reference file in the following code, and it compiles:

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}

\begin{document}

\nocite{*}
\bibliographystyle{plain}
some text bla bla bla

\bibliography{library}
\end{document}

The command \nocite{*} is used to print the entire bibliography, then you need to run pdfLaTeX + BibTeX + pdfLaTeX + pdfLaTeX.

It should work fine.

A variant with the package biblatex is the following:

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[backend=bibtex, natbib=true]{biblatex}

\bibliography{library}

\begin{document}

\nocite{*}

some text bla bla bla

\printbibliography[heading=bibintoc]
\end{document}

Ps: i) The bibliography does not print if no command \cite{.} are found, hence the \nocite{*} instruction.

ii) If you do not have the bibliography style authoryear, bibTeX will complain and say "couldn't open style file authoryear.bst " and the bibliography won't show up...

Hope that helps.
