The study of memory straddles a wide range of social science disciplines including sociology, psychology, anthropology, and geography. Within sociology, reviews of the literature have already been carried out, but these are now somewhat dated. This article takes the measure of recent prior research on the sociology of collective memory and commemoration by (1) proposing a classification of collective memory research; (2) organising the literature under the headings of theoretical developments, methodological strategies, and methodological challenges; and (3) offering suggestions for maximising the internal cohesion and external utility of the sub-field.
