Genre theorists agree that genres work together in assemblages.But what is the nature of these assemblages? In this paper I
describe four frameworks that have been used to describe
assemblages of genres: genre sets, genre systems, genre
repertoires, and genre ecologies. At first glance, they seem to be
interchangeable, but there are definite and sometimes quite deep
differences among them. I compare and contrast these frameworks
and suggest when each might be most useful.
