% KTM's conventions:

% A citation is built up from segments, each on a different line:
% 1. \bibitem{label}
% 2. authors.    use the macro \etal is appropriate.  (\def added to prst00.tex)
% 3. title    -- in the published version, Phys. Rev. may want us to suppress 
%             the titles.  Easy to do with %'s at beginning of lines.  However,
%             in our own version of the document, I greatly prefer having the
%             title available, giving the reader more of an idea what the
%             reference is about.
% 4. where published.   
% 5.  URL, if available.

% Authors names always have ~ in them; only initials are used for other than
% the last name: J.~C.~Gallardo
% (Usually I write `J.C.~Gallardo', suppressing the space between multiple
% initials.  But this document seems to have started with the space present,
% so I continue to follow that convention.

% The title of an article is thus; {\sl Title of Article}

% Published book titles (including conference proceedings are thus: 
% {\em Title of Book}

% Conferences with proceedings published in the AIP series are referred to
% in journal style: AIP Conf. Proc. Vol, page (year).

% Put a \ after a . in an abbreviation: AIP Conf.\ Proc.\ {\bf nn}, mm (19oo).

% Names of conferences with as yet unpublished proceedings are in plain text.

%  I have made only intermittent use of `unpublished' -- and do not put
%  this in parentheses.
%  I consider that preprints without a citation of a publication are
%  obviously unpublished.  Conference proceedings are ambiguous, so Inq
%  use `unpublished' for them, if appropriate.

% Each URL is on a separate line, with no additional punctuation,  I use
%    \hfill\break to force a new line.
% I have defined the symbol `\~' to insert a ~ in Unix directory abbreviations.
% The other symbol useful in URL's, `\_', is a LaTeX standard.

% I have tried to assemble a block of references to the many muon collider
% workshops.  Then when articles/presentations at one of these workshops
% are referred to, I point back to the primary reference for the gory details,
% so as not to repeat the lengthy citation thereof.  However, I do add
% the date to the citation of the article, to give the reader a quick clue
% as to the timeliness of the article.  [Maybe should drop this???]
%
% Personally, I consider the many citations `private communication' to be
% in bad taste -- we are hiding behind a lack of work on our part.  However,
% I have let most of them stand, as such a citation is somewhat better than
% none at all.
