When referencing to another work in a scientific paper, do we cite the paper or its author(s)?
This question is intended to clarify the conjugation of the verb that follows the reference — especially in these cases:
One author, two papers:
Jane Doe (2015a, 2015b) list-s the very specific conditions under which…
-> lists (singular: referencing to Jane Doe) or list (plural: referencing to both papers)
Several authors, one paper:
John Doe, et al. (2015) claim-s this and that.
-> claim (plural: referencing to the multiple authors of the paper) or claims (singular: referencing to the single paper).
