In the late 1980s, I wrote up some notes on the play of pick-up basketball and sent them to Harold Garfinkel, who incorporated them into an un-published monograph in 1988. They were motivated by an interest in exhibiting the sense of "detail" for ethnomethodological studies. An edited version is presented below. They follow a front piece of recollection and discussion about Garfinkel's distinctive interests in matters of "detail," their tie to structure and structure's circumstantiality, and their place in EM studies.
