In preamble:
\usepackage{collref}
\collectsep{;\ }
before \end{document}
\bibliographystyle{h-physrev4}
\bibliography{thdmiii}
The idea is use easy labels in the \cite of the latex file and the use the
scripts to generate proper referencia in the inspire format.
Inside the
LaTeX document you can use arxiv numbers or journal-like references, then
$ texkey
to convert to inspire texkeys and the use to
$ bibtexspires
and, optionally
$ bblspires
Check the help in each script for further information
