% Construction of the cite key:                                        %
%    All letters are in lower case. The key starts with the last       %
%    name of the first author followed by two numbers identifying      %
%    the publication year. The key ends with the first letter of       %
%    the first three words in the title of the paper. For most         %
%    papers this key is unique. However, if the first three words      %
%    are equal, we use the first three letters followed by a           %
%    positive number (e.g. 1, 2, 3,...). If the title consists of      %
%    less than three words, we still use only the first letter of      %
%    each word.                                                        %

% If you do not find the correct key, you should just search through   %
% the file looking for one of the authors. There are a number of ways  %
% to do this, use e.g. your favorite text editor or the UNIX tools     %
