General ⇒ Harvard dcu bibstyle multiple authors entry

[emmesalani]

Hi all,

I ask for your help with bibtex and harvard style

from the following bibtex entries

@Article{ABC2008,
authors= {famNamA and famNamB and famNamC},
year = {2008},
...
}

@Article{ABCD2008,
authors= {famNamA and famNamB and famNamC and famNamD},
year = {2008},
...
}

basically two similar entries with an author more (at the end)

I would like to obtain the following citations

famNamA, et al. (2008a)
famNamA, et al. (2008b)

using basic commands like

\citeasnoun{ABC2008}
\citeasnoun{ABCD2008}

bibtex produces

famNamA, famNamB and famNamC (2008)
famNamA, famNamB, famNamC and famNamD (2008)


so far different styles produce the same effect

should I use particular citation commands? or should I customize the dcu style?


Thanks to anybody answering...
