Our particular interest is in the possibilities surrounding the use of ethnographic material and in the contribution this might make to CSCW design. in this paper we focus on outlining some of our experiences and difficulties in developing patterns from ethnographic studies and present some initial ideas towards the development of a pattern langiage to exploit the experience gained from a decade of field studies.enText10.1007/0-306-48019-3
