har2nat package written by Bas Straathof, 2005/12/01 Eindhoven University of Technology, The Netherlands bas.straathof@gmail.com. This small package allows a LaTeX document containing the citation commands provided by the Harvard package (Peter Williams and Thorsten Schnier) to be compiled using the natbib package (Patrick W. Daly). Migration from harvard to natbib thus can be achieved simply by replacing \usepackage{harvard} with \usepackage{natbib} \usepackage{har2nat} ---IMPORTANT--- har2nat must not be loaded before the natbib package as it redefines the natbib commands \cite and \citeyear. All other natbib commands remain unchanged and can be used alongside the Harvard commands.
