% The following statement selects the style to use for references.  It controls the sort order of the entries in the bibliography and also the formatting for the in-text labels.

\bibliographystyle{abbrvnat}
% This specifies the location of the file containing the bibliographic information.
\cleardoublepage % This is needed if the book class is used, to place the anchor in the correct page,
                 % because the bibliography will start on its own page.
                 % Use \clearpage instead if the document class uses the "oneside" argument

\phantomsection  % With hyperref package, enables hyperlinking from the table of contents to bibliography
% The following statement causes the title "References" to be used for the bibliography section:
\renewcommand*{\bibname}{References}
