Doing It By Hand

Hand coding is accomplished much the same as described in (, p. 73) except that the new command \harvarditem is used in place of \bibitem. The syntax of this command is
\harvarditem [abbr-citation]{full-citation}{citation-year}{cite-key}
where
abbr-citation
is the (optional) abbreviated citation (minus the year) to be used in the text subsequent to the first mention of a particular reference,
full-citation
is the full citation (minus the year) to be used in the text on the first mention of a particular reference,
citation-year
the year portion of the citation including any suffices required to disambiguate citations, and
cite-key
is the key used in the \cite and \citeasnoun commands.
