Extra "by " after reviewed author
When using either chicago-author-date.csl or apa.csl, an extra "by " is inserted after the reviewed-author:
Reviewer, Rob. 2015. “A Clever Title.” Review of My First Book, by Ann Authorby . Journal of This and That 15 (3): 244–48.
This, the fact that deleting chicago-author-date.csl#L217 leads to the removal of both "by "s, and the fact that pandoc-citeproc does not insert this extra "by " with either of the two styles might suggest this could be a citeproc-js issue rather than a style issue, but I’m not sure, of course. Any ideas?
