I always get this warning from using Bibtex : There is a number but no volume in ... Empty journal in ...

Could anyone tell me what is wrong here, how to correct this?

I am using TeXnicCenter and MikTeX package.

    Check your BibTeX entries and make sure that there is a volume field in all those that contain a number field. – jub0bs May 4 '13 at 14:53

    Bib entries of type @article require journal and volume fields (as well as author, title and year fields...). The number and pages fields are optional. Check if there's some information missing in the bib entry in question. If the entry doesn't have information suitable for the volume field, you should maybe consider using a different entry type (such as @misc) altogether. – Mico May 4 '13 at 15:01

BibTeX returns that error if you reference one or more @article entries that have a number field but lack a volume field. For instance, if you run pdflatex, bibtex on

\documentclass{article}

\usepackage{filecontents}

\begin{filecontents*}{mybiblio.bib}
@article{Jubobs:2013,
    author  = {Jubobs},
    title   = {{How} to stay away from {TeX.SE} for a solid hour},
    journal = {International Journal of Addiction},
    year    = {2013},
    number  = {2},
    pages   = {104--111},
}
\end{filecontents*}

\begin{document}
See \cite{Jubobs:2013} for further details.
\bibliographystyle{plain}
\bibliography{mybiblio}
\end{document}

BibTeX will return the following warning:

Warning--there's a number but no volume in Jubobs:2013

If you run pdflatex twice after that, the output will be:

The cause of that error has been given by Mico in a comment above: the volume field is mandatory in an @article BibTeX entry. (Note that BibTeX also returns an error, albeit a different one, if one or more @article entries contain neither volume nor number fields.)

If you add a volume field to that BibTeX entry, for instance volume = {11}, and then run pdflatex, bibtex, pdflatex, pdflatex, BibTeX will not return any error, and the output will be:

    +1, particularly for the reference! I'll read it with great interest, if I find the time to stay away from TeX.sx. ;-) – egreg May 4 '13 at 15:19
