# With bibliography style “achemso” publishing years of books aren't bold

I'm currently using achemso as my bibliography style. And i have to cite some books, but unlike for papers the publishing year for the books does not appear in bold numbers. Does anybody have an idea how to change that? I have only tried putting \textbf{} in the .bib file but that produces an error (improper alphabetic constant) and i read that there are only numbers allowed in the "years bracket".

Well here is my example:

\documentclass{scrreprt}
\usepackage[super,square,sort&compress,comma]{natbib}

\begin{document}

See XYZ\cite{Reichardt2004,Clark2006}

\bibliographystyle{achemso}
\bibliography{Bibliography}
\end{document


and these are the .bib entries:

@Article{Clark2006,
Title                    = {Green chemistry: today (and tomorrow)},
Author                   = {Clark, James H.},
Journal                  = {Green Chem.},
Year                     = {2006},
Pages                    = {17-21},
Volume                   = {8},

Issue                    = {1},
Publisher                = {The Royal Society of Chemistry}
}

@InBook{Reichardt2004,
Title                    = {Front Matter},
Author                   = {Reichardt, Christian},
Pages                    = {i--xxvi},
Publisher                = {Wiley-VCH Verlag GmbH \& Co. KGaA},
Year                     = {2004},

Booktitle                = {Solvents and Solvent Effects in Organic Chemistry}
}


And here is how it looks for me:

I use TeXnicCenter 2.02 and Miktex 2.9. Compiling: LaTex -> PS -> PDF

Thank you very much for your help!

• This is 'by design': the ACS only use bold for the year for journal articles. – Joseph Wright Dec 10 '14 at 12:18

THE ACS only use bold for years when the entry is a journal: other types of reference do not have this formatting. As such, the achemso style simply does what is 'required'.
