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

% 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
\hypersetup{setpagesize=false, a4paper=true, colorlinks=true,linkcolor=blue, urlcolor=blue,citecolor=black}

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.

TIA for your suggestions.

  • 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
  • @Davide If I do not load the unithesis package, it might work. The problem with this is that without loading this package, I would not be able to author my thesis, as it is the prescribed package for the uni. – Vinod Dec 29 '15 at 12:23

    Nobody of us knows package unithesis` (very creative name by the way) nor your requirements for submitting a thesis. I would ask the maintainer of the package for advice and pointers. – Johannes_B Jan 7 '16 at 8:05
