I am preparing a case study of a social work professional organisation which is non-existent now but had a glorious past. For this, I interviewed around 20 members of the association to understand the organisation's trajectory and fall. The respondents are well known academicians and are also people who contributed to the growth of the organisation through its various stages.
Now, in the report, while presenting the results of the study, I am using the quotations from the interviews to capture the journey of the organisation and the role played by these people. Would it be violating confidentiality or ethics, if I tag their names to the quotations used? Except one, none of them asked me to keep their information confidential. I strongly feel that giving names to quotations is important to add historical documentation value to the research report. I look forward to suggestions and advice.
