Dear Professor Manners,
Suppose a colleague shares a paper with you in an area of philosophy you don’t work in. And suppose the bibliography contains no citations to women. You’d like to point this out, politely, but since this is not your area, you don’t know the literature and thus can’t point the paper author to particular articles written by women that might be consulted/cited. (And it would be a non-trivial and time-consuming matter to do the literature review yourself.) You really don’t want to stay silent about this, but you are feeling somewhat vulnerable for various reasons. What is the best way to proceed?
Timid but troubled
