# Links to bibliography from main text in pdflatex [closed]

In my thesis, I am loading the hyperref package. The thesis package itself loads the harvard package. Here is the snippet of the relevant packages from my main thesis.tex file:

% dissertation style file
% loads the harvard package by default
\usepackage{unithesis}
\usepackage{hyperref}
\usepackage{cite}

% Use the first here for colored links in the PDF output file
% use the second for printed output (black text only)
% Note also that the setpagesize=false is necessary to stop
% hyperref resetting the page size back to Letter


I am following the below notation in my .bib file. For example, to cite a journal article, I use:

@article {REF1,
author = {Gassmann, Oliver and Zeschky, Marco},
title  = {{Opening up the Solution Space: The Role of Analogical Thinking for Breakthrough Product Innovation}},
journal = {Creativity and Innovation Management},
volume = {17},
number = {2},
publisher = {Blackwell Publishing Ltd},
issn = {1467-8691},
doi = {10.1111/j.1467-8691.2008.00475.x},
pages = {97--106},
year = {2008},
}


I want references from my main text to my bibliography. For instance, if I use \cite{REF1} in my main text, I should get a hyperlink to the above mentioned reference in my bibliography. That is not happening now. I googled for answers and also tried looking up previous posts, but could not find anything that resolved my problem. For instance, the following link discusses the same issue, but I could not figure out how to fix the issue from the answer:

In Latex, how do I create citations to references with a hyperlink?

Can anyone help me resolve this without loading any additional packages that would clash with the packages already loaded in my style sheet? I mention this because in another link related to the issue, the suggestion was to load the natbib package:

Citation call-out, with hyperlink, to manually-input bibitem

But if load the natbib package, it messes my style sheet and I get the following error:

! LaTeX Error: Command \harvardurl already defined.
Or name \end... illegal, see p.192 of the manual.
See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.


• Does the problem persist if you don't load the unithesis package? if so, you should try and set up a mwe – Davide Dec 29 '15 at 10:55
