I recently encountered some behavior with the chicago-author-date csl that surprised me, and I’m wondering if anyone can provide any insight.
According to 15.30 in the Chicago Manual of Style, two works by the same author cited in succession without page numbers should be separated by a comma:
Additional works by the same author(s) are cited by date only, separated by commas except where page numbers are required.
(Whittaker 1967, 1975; Wiens 1989a, 1989b)
(Wong 1999, 328; 2000, 475; García 1998, 67)
The relevant example is
Whittaker 1967, 1975, where a comma is used to separate the two works of the same author (when no page numbers are used).
Given that, I was surprised to see the following results while using Zotero to preview citations for works by the same author, using Chicago’s author-date style (17th edition):
In the Single Citation, the years are separated by a semicolon rather than a comma. Compared to the example in the manual, this behavior seems incorrect—given that no page numbers are present.
Likewise, I am seeing the same behavior in Microsoft Word while using the Zotero plugin with the csl set to chicago-author-date (17th edition):
This is a sentence (McDaniel 2005; 2009; 2012).
If anyone has any pointers that might help, please let me know. If not, I wonder if this behavior might stem from the chicago-author-date csl itself?
