Comma before "&" when adding more than two authors in Zotero

Hi everyone,

I’ve been experiencing an issue with Zotero when adding more than two authors to my references. For some reason, a comma is automatically inserted before the "&" symbol, which is not consistent with the citation style I’m using (APA7). Here's an example of the output I get:

Doe, J., Smith, A., & Johnson, B.

I need the output to look like this without the comma before "&":

Doe, J., Smith, A. & Johnson, B.

Has anyone else encountered this problem? Is there a way to fix this in Zotero's settings or a specific style to use that removes the extra comma?

Thanks in advance for your help!

Best regards,
Kari
  • APA style _does_ call for a comma to be given in this position. Zotero is producing correct citations according to the APA manual
  • Hi!

    I am looking for exact the same issue.
    Zotero is correctly citing APA7 with comma before ‘&‘:
    Doe, J., Smith, A., & Johnson, B.

    But in the german adapted APA7-rules, there is no comma before ‘&‘:
    Doe, J., Smith, A. & Johnson, B.

    So maybe someone can explain how to remove this for a APA7-german style?
    I would be very happy if you can explain :)

    Thanks so much in advance!
  • Thanks so much for your quick reply on this!

    Unfortunately the style you recommended is the old APA 5th. But I guess I found out what to change in the csl :)

    When I change entries in for
    delimiter-precedes-last="always"
    to
    delimiter-precedes-last="never"
    it is doing exactly what is requested by the profs.

    I have no clue, how to give this to other people, but I think you may help ...

    Thank you!
