BibTex in journal template APS

Question

I'm trying to get working bibliography in this APS journal template (https://it.sharelatex.com/templates/journals/aps).

Using commands for BibTex found online it's not working. For example:

\cite{comune:1}

Just before \end{document}:

\bibliography{bib}

And after \begin{document}:

\bibliographystyle{plainnat}

So in the same folder i put a file bib.bib that contains the entry:

@ONLINE {comune:1,
    author = "Comune di Manfredonia",
    title  = "Preferenze Consiglio comunale - Riepilogo generale per Lista",
    month  = "may",
    year   = "2015",
    url    = "http://www.comune.manfredonia.fg.it/attivitaservizi/elettorale/ele2015/index.htm"
}

But this way it just doesn't show anything. What is going on?? Thank you

[UPDATE] Compiling BibTex (F11) and then two time PDFLatex (F6) i had the bibliography. But why link is splitted over two columns?

Answer 1

(Too long for a comment, hence posted as an answer.)

In the following example, I load the revtex4-1 document class, since that's also the document class loaded by the template file you've provided a link to.

Observe that I would encase the contents of the author and title fields in curly braces in order to (a) inform BibTeX that the author is a "corporate" author (rather than a person whose first name is "Comune", whose "von" component is "di", and whose surname is "Manfredonia") and (b) to prevent BibTeX from lower-casing the words in the title field. I would further like to recommend you issue the instruction \raggedright immediately before \bibliography.

The following code appears to compile fine under ShareLaTeX.

\RequirePackage{filecontents}
\begin{filecontents}{bib.bib}
@misc{xyz,author="ABC",title="DEF",year=3001}
@ONLINE{comune:1,
    author = "{Comune di Manfredonia}",
    title  = "{Preferenze Consiglio comunale---Riepilogo generale per Lista}",
    month  = "Maggio",
    year   = "2015",
    url    = "http://www.comune.manfredonia.fg.it/attivitaservizi/elettorale/ele2015/index.htm"
}
\end{filecontents}

\documentclass[ reprint,amsmath,amssymb, aps]{revtex4-1}
\bibliographystyle{plainnat}
\usepackage[italian]{babel}

\begin{document}
\cite{comune:1}, 
\cite{xyz} % dummy entry

\raggedright  % <- recommended
\bibliography{bib}
\end{document}
