hey all, this might have come up before so pardon me if this is repetitive. I am interested in doing a content analysis of texts within an email archive. and I was wondering how to deal with IRB issues in this case. specifically, I am focusing on the text and not the authors. if I did need informed consent its seems impractical to get given the number of participants (several hundred) and age (over 5 years) of some of the emails. what should I do in that case? also, what would be the approach if the archive is available publicly or if its private? finally, are there any other major IRB requirements that I should consider in this type of exercise? thanks Dhanaraj Dhanaraj Thakur Ph.D. Student School of Public Policy Georgia Institute of Technology
