Use the natbib package. It provides commands like:

\citet{jon90}     -->  Jones et al. (1990)

\citet[chap. 2]{jon90}    --> Jones et al. (1990, chap. 2)

\citep{jon90}    --> (Jones et al., 1990)

\citeauthor{jon90} --> Jones et al.

\citeyear{jon90} --> 1990

Use the natbib package. It provides commands like:

By clicking on this, the reader will 'jump' to the section References, where this author is already in the list, like this:

\bibitem{Bharathi03}

Bharathi A.M.\index[people]{Bharathi A.M.}, Kumar S.C.\index[people]{Kumar S.C.}, Kalliappan S.\index[people]{Kalliappan S.} 2003. \emph{Target Identification in multispectral images using \textit{in-situ} hyperspectral reflectance}. The Geospatial Resource Portal. Remote Sensing.

\href{www.gisdevelopment.net}{gisdevelopment} \pageref{Bharathi03}

By the way: the last link \pageref{Bharathi03} will make the reader 'jump' back to the main body text where he was cited.
