I was trying to cite two papers written in the same year but by different authors. The bibliography package I used was \usepackage{natbib}.
...
\usepackage{natbib}
\begin{document}
\cite{pchan02} argues that.... However, \cite{mchan02} points out a problem...
\bibliography{listwork}
\bibliographystyle{custom1}
\end{document}
However, the output I got was:
'Chan (2002a) argues that.... However, Chan (2002b) points out a problem...'
The same with the bibliography list at the end: 'Chan, Peter. 2002a. ...' 'Chan, Mary. 2002b. ...'
It seems that natbib judges whether two authors are the same just by the family name. In this case, the two Chan's are actually different authors ('Peter Chan' vs. 'Mary Chan'). So, the desired output for me would be:
'Chan (2002) argues that.... However, Chan (2002) points out a problem...'
Is there a way I can change things so two authors would be taken to be the same only when the both the first and surnames are identical? That is, if I'm citing two works by Susan Chan in the same year, I'd like the outputs of \cite{schan07a} and \cite{schan07b} to be exactly 'Chan (2007a)' and 'Chan (2007b)' (and I have no problem with this; my compiler gave me exactly these outputs.) The problem I have is that two different authors with the same surname are also treated the same person, incorrectly.
Any help would be greatly appreciated. Thanks! (I searched for similar questions on StackExchange, but the solutions are inapplicable in my case. I'm using natbib.)
Here's a list of entries from the listwork.bib file:
@article{pchan02,
title={The meaning of life},
author={Chan, Peter},
journal={Journal of Happiness},
pages={1--3},
year={2002},
}
@article{mchan02,
title={On the meaning of the meaning of life},
author={Chan, Mary},
journal={Journal of Happiness},
pages={4--6},
year={2002},
}
@article{schan07a,
title={On meaning},
author={Chan, Susan},
journal={Journal of Happiness},
pages={10--13},
year={2007},
}
@article{schan07b,
title={On the meaning of meaning},
author={Chan, Susan},
journal={Journal of Happiness},
pages={14--16},
year={2007},
}
