This research project is the result of collaboration by the following organisations:- The King's Fund; London Boroughs Training Committee; London Voluntary Services Council; National Institute of Social Work; Age Concern Greater London. It was financed by the King's Fund. The limits of altruism explores the social and psychological processes which influence collaborative work. Starting with the elderly person in need, and his/her relationships with informal carers, it goes on to examine the strengths and weaknesses in much existing support as reflected in the experiences of both service providers and users.
