Standard BibTeX styles conform to a scheme for managing the letter
case in various parts of citations (notably titles). This can be
extremely tiresome: you may find "Einstein
" appearing as
"einstein", "CO
" (for Carbon Monoxide) as "co"; sometimes
these changes can entirely alter the sense of a title, but mostly
they're merely tiresomely bad typesetting.
Fortunately, BibTeX's language provides a "leave it alone, please" syntax: enclose the stuff to be 'ignored' in braces. So you might change:
TITLE = "On Einstein's theory of CO control",\begin{pdfversion}
TITLE = "On Einstein's theory of CO control",\end{pdfversion} \begin{dviversion}
TITLE = "On Einstein's theory of CO control",\end{dviversion} to: TITLE = "{On Einstein's theory of CO control}", \begin{pdfversion} TITLE = "{On Einstein's theory of CO control}", \end{pdfversion} \begin{dviversion}
TITLE = "On {E}instein's theory of {CO} control",\end{dviversion} or even: TITLE = "{On Einstein's theory of CO control}", \begin{pdfversion} TITLE = "{On Einstein's theory of CO control}", \end{pdfversion} \begin{dviversion}
TITLE = "{On Einstein's theory of CO control}",\end{dviversion} Which last says "I know what I'm doing, you needn't bother with it, BibTeX"; it's a useful form if there are lots of names or chemical formulae, or whatever in a title.
BibTeX also makes a hash of accents: "ma\ nana
" comes out as
"ma nana" (!). The solution is similar: enclose the troublesome
sequence in braces, as "{\ n}
".
