Peer-Reviewed Journal Article

Journal articles that passed formal academic peer review before publication, this atlas's highest evidentiary tier for a scholarly claim. Belongs here: a citation to an article published in a peer-reviewed linguistics, anthropology or related academic journal. Does not belong here: a standalone monograph or book-length academic reference work, each its own separate source kind, or an unreviewed academic paper accessed only through a search summary, which carries materially weaker evidentiary weight and is tracked separately.
