Harvard and multiple authors with same year publication

c.c.currie88

Hi,

I'm using Harvard referencing style but when there is more than one author with the same surname and year of publication the in-text citation includes the author's initials rather than add a suffix of a, b, c etc to distinguish between them. For example, (M. A. Peres et al., 2019) rather than (Peres et al., 2019a). If it's the same author and same year it does add the suffix instead. I know this is correct for some Harvard formats, however for the format I need to use I need to delete the author initials and use an alphabetical suffix instead. Is there a way of changing this in Zotero or will I need to do it manually at the end? I'm currently using the style "Elesvier - Harvard (with titles)".

Thanks

Hi,

"Harvard" means "author date", nothing more.

Are you publishing in a certain journal?

c.c.currie88

It's for a PhD thesis so stipulated by the university.

Well, you can search for your uni here: https://www.zotero.org/styles
With a bit of luck, you might find a style.

If Elsevier Harvard fits otherwise, you can edit that style: https://www.zotero.org/support/dev/citation_styles/style_editing_step-by-step

Set disambiguate-add-year-suffix="true" to false or delete it.

Thanks. Having checked with the university they say to use Cite Them Right 10th edition - Harvard (no "et al."). This creates the right formatting but doesn't add the alphabetical suffix when it's the same author and date? How would I change that please?

We have those styles on the repository.

Thanks, yes I've found the styles but the "Cite Them Right 10th edition - Harvard (no "et al.")" doesn't then include the alphabetical suffix to denote the same author with the same date of publication so need to change that part please?

E.g.
Allareddy, V., Rampa, S., Lee, M.K., Allareddy, V. and Nalliah, R.P. (2014) ‘Hospital-based emergency department visits involving dental conditions : Profile and predictors of poor outcomes and resource utilization’, Journal of the American Dental Association, 145, pp. 331–337.
Allareddy, V., Rampa, S., Nalliah, R.P. and Allareddy, V. (2014) ‘Longitudinal discharge trends and outcomes after hospitalization for mouth cellulitis and Ludwig angina’, Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology, 118, pp. 524–531. doi:10.1016/j.oooo.2014.06.003.

Should be:
Allareddy, V., Rampa, S., Lee, M.K., Allareddy, V. and Nalliah, R.P. (2014a) ‘Hospital-based emergency department visits involving dental conditions : Profile and predictors of poor outcomes and resource utilization’, Journal of the American Dental Association, 145, pp. 331–337.
Allareddy, V., Rampa, S., Nalliah, R.P. and Allareddy, V. (2014b) ‘Longitudinal discharge trends and outcomes after hospitalization for mouth cellulitis and Ludwig angina’, Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology, 118, pp. 524–531. doi:10.1016/j.oooo.2014.06.003.

The same fix as explained above works. It's the same setting that achieves the same output in both styles.

Hi there

I have exactly the same problem but with APSA 7th edition. I've used this style (though not sure if same edition) already many times and never had a problem, it always put the letters automatically.

I am wondering if something changed, since it sais that there was some update on Nov. 19 2021...

Corinne, thank you for your comment, but please don't hijack other people's threads.

We implement styles based on the official guidelines. If you do think that there is indeed an error, please let us know. But in this case, APSA was last updated in 2015.
If you mean APA, that's our most well-established, widely used and reviewed style.

c.c.currie88

I've tried that now but it hasn't changed anything. The references with the same author and year are still missing the alphabetical suffix after the year. And now some of the references in text are listing more than three authors rather than using et al.

damnation

Ah, you want the reverse.
Then remove disambiguate-add-names="true" disambiguate-add-givenname="true" and put the other one back in.

Also make sure you follow this guide and give the style a unique ID etc. as explained: https://www.zotero.org/support/dev/citation_styles/style_editing_step-by-step

c.c.currie88

Still not quite there. It's now differentiating between them by adding more author names to the in-text citation rather than adding a letter. E.g.
Allareddy, Rampa, Lee, et al., 2014
Allareddy, Rampa, Nalliah, et al., 2014

Rather than
Allareddy et al. 2014a
Allareddy et al., 2014b

The code I have is

c.c.currie88

citation et-al-min="1" et-al-use-first="1" disambiguate-add-year-suffix="true" disambiguate-add-names="false" disambiguate-add-givenname="false" collapse="year"

damnation

elsevier-harvard.csl works as expected with these settings:

Don't use et-al-min="1" though -- you want et-al-min="3" -- the 1 doesn't make sense, so I could see this would lead to odd behavior.
