Swales, J. M. (1990). Genre Analysis: ENglish for academic and research purposes. Cambridge: Cambridge University Press.

Chapter 2 of this book is on discourse communities and here are the criteria Swales proposes for defining discourse communities.

1. A discourse community has a broadly agreed set of common public goals.
2. A discourse community has mechanisms of intercommunication among its members.
3. A discourse community uses its participatory mechanisms primarily to provide information and fedback.
4. A discourse community utilizes and hence possesses one or more genres in the communicative furtherance of its aims.
5. In addition to owning genres, a discourse community has acquired some specific lexis.
6. A discourse community has a threshold level of members with a suitable degree of relevant content and discoursal expertise. (pp. 24-27)
