+ % This bibliography style file is intended for texts in ENGLISH

+ % This is a numerical citation style, and as such is standard LaTeX.

+ % It requires no extra package to interface to the main text.

+ % The form of the \bibitem entries is

+ %   \bibitem{key}...

+ % Usage of \cite is as follows:

+ %   \cite{key} ==>>          [#]

+ %   \cite[chap. 2]{key} ==>> [#, chap. 2]

+ % where # is a number determined by the ordering in the reference list.

+ % The order in the reference list is that by which the works were originally

+ %   cited in the text, or that in the database.
