The Routledge Guide to Interviewing sets out a well-tested and practical approach and methodology: what works, difficulties and dangers to avoid and key questions which must be answered "before" you set out. Background methodological issues and arguments are considered and drawn upon but the focus is on what is ethical, legally acceptable and productive:
Rationale (why, what for, where, how)
Ethics and Legalities (informed consent, data protection, risks, embargoes)
