  % 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.
