Julia Gannon explores the findings of a study into the recording style and content of adoption files and the influences of these on the birth record counsellor's decision-making process. Her article focuses on the specific information shared or not shared with the adopted adult. It asserts that birth record counselling is one of the few tasks that propel the social worker back into the history of social work practice while simultaneously supporting service users through their search for information about their birth history and adoption. There is an emphasis on assessing how serviceable the recording style and content of adoption files are for adoptees. The research design involved semi-structured interviews with eight social workers currently holding birth record counselling cases. Four of the respondents were employed in local authority adoption teams and four were independent self-employed social workers in the field of adoption. The author's findings suggest that the knowledge birth record counsellors' gain from adoptees about how they experience their files has potential for practical application to social work practice in children and families teams today.
