Q. In instances where you have several citations from the same author and year (with lettered years to denote separate sources) within the same in-text citation, would it be acceptable to use an en dash instead of writing out each year? For example: “(Soil Survey Staff 2021a–2021d)” rather than “(Soil Survey Staff 2021a, 2021b, 2021c, 2021d).”
A. Yes, that works well. The only caveat is that if your citations will be linked to their corresponding entries in the reference list (as they are in the HTML versions of the articles in the American Journal of Sociology), then you’ll need to list each lettered year to facilitate separate links.
