This newly published book chapter by Tara Murphy, Aileen O'Carroll, Suzanne Guerin and Jane Gray discusses some of the ethical and practical issues involved in archiving social science research data, with specific emphasis on data arising from community change initiatives. The chapter highlights and addresses some of the key concerns raised by researchers, including informed consent, data ownership and the management of confidentiality and anonymity. Findings are based on a case study of a community initiative (Tallaght West Childhood Development Initiative) to provide instances of where community evaluation research might present some additional challenges relating to archiving, and to identify ways of overcoming those challenges.
