In my field it is common to have shared first authorship for authors who “contributed equally to the work” (as shared first authorship is usually defined). The “proper” way of citing publications with shared first authors is to mention all first authors (not just the first first one1).
Now, normally the citation style for
authordate-like formats is along the lines of:
Doe, Jane et al. (1995), “Title”. In: Journal
Whereby the subsequent authors are elided2. However, with shared first authors, the citation should look like this:
Jane Doe, Fred Foo et al. (1995), “Title”. In: Journal
I have two (related) questions concerning this:
- How do I accomplish this citation style in LaTeX using BibLaTeX?
- How do I even mark shared first authors in the source
The second question is a corollary of the first, since it is my understanding that in a “normal”
*.bib file the
author field is simply an ordered list, with no means of indicating contribution.
I’m particularly interested in how to accomplish this for
authoryear style; however, I’m also interested in a more general solution with full author lists (in which joint first authors could e.g. be marked by an asterisk).
1 And this is actually quite important, although disappointingly few publications get it right, because if not done, it skews authorship for the purpose of text mining, and unfairly withholds the equal contributions of the co-first authors.
2 Unless there are very few (e.g. < 3), in which case it’s common to cite them all.
