acknowledgements in these volumes, Jefferson mentioned the help of Sudnow in dealing with Sacks's literary estate. The Harvey Sacks Memorial Association, registered as a not-for-profit Association, was formed by Sudnow. These Lectures have been important for Sacks's later influence and for the field of Conversation Analysis. Sudnow was a follower of Alfred Schutz in phenomenology, and Harold Garfinkel in ethnomethodology. Sudnow regards the work of Sacks as outside the ethnomethodological mainstream. By contrast Garfinkel lists Sacks as one of 'Ethnomethodology's Authors' Works Sacks, H. (1963) "Sociological Description," in Berkeley Journal of Sociology, 8:1–16. Sacks, H.
