-% Although synthetic chemists do not, in the main, use LaTeX for the
-% preparation of journal articles, it would be nice to be able to use
-% it for reports.  Some (mainly) physical chemistry journals do
-% also accept LaTeX submissions, and so the need for BibTeX styles
-% for chemistry is real. The package |achemso| provides for a BibTeX
-% style and other support for articles and reports in the style of
-% the American Chemical Society (A.C.S.).  Journals which use the
-% standard A.C.S. citation style are summarised in
-% \ref{tbl:journals}.
+% Synthetic chemists do not, in the main, use LaTeX for the
+% preparation of journal articles. Some journals, mainly in the
+% physical chemistry area, do accept LaTeX submissions.  Given the
+% clear advantages of LaTeX over other methods, it would be
+% nice to be able to use LaTeX for preparing reports. Thus the need
+% for BibTeX styles for chemistry is real. The package |achemso|
+% provides for a BibTeX style and other support for articles and
+% reports in the style of the American Chemical Society (ACS).
+%
+% As describe in \emph{The ACS Style Guide} \cite{Coghill2006},
+% almost all ACS publications use the same style for the formatting
+% of references.  The reproduction of this style is the aim of the
+% BibTeX style file provided here.  However, the ACS use different
+% citation styles in different publications.  The |achemso| package
+% provides support for the two numerical systems: superscript
+% and italic in-text citations.  The majority of ACS journals use
+% the superscript method (Table \ref{tbl:journals-super}), with a
+% smaller number using the italic system (Table
+% \ref{tbl:journals-inline}). The journal \emph{Biochemistry} does
+% not use the standard ACS style for references, and so is not
+% covered by the |achemso| package.
