In my field, conferences are rarely peer reviewed. The usual categories of peer review are journals and grants. If I peer review for conference proceedings, should I list that in my CV under journal peer reviewing, or should I create a new category?
Maybe you can go with a broader heading so you can group them all together - something like "Manuscript Reviewing" will cover a myriad of publication categories, like conference proceedings, journals, edited volumes, etc. EDIT: Would also add that in doing so, the reader would then automatically know that those are all peer-reviewed venues.
