Forensic linguistics is at the cutting edge of the undercover policing of child sexual abuse on the open internet and dark web, and language and identity is a fundamental part of this. The authors have drawn on their extensive experience in training undercover officers to develop innovative methods in identifying the creation and performance of online personas, crucial in detecting identity disguise online. This groundbreaking book demonstrates these methods through case studies, whilst also exploring the link between language and identity. By bringing together previously opposed positions in forensic authorship analysis, the book develops a novel theory of linguistic identity, which will resonate not just in forensic authorship research but in sociolinguistics more widely. This unique forensic linguistic project has real-life impact in assisting the police in their investigation of online abusers, and has impact for students and researchers of linguistics, through its contribution to the research of linguistic identities.

This Element examines progress in research and practice in forensic authorship analysis. It describes the existing research base and examines what makes an authorship analysis more or less reliable. Further to this, the author describes the recent history of forensic science and the scientific revolution brought about by the invention of DNA evidence. They chart the rise of three major changes in forensic science ¿ the recognition of contextual bias in analysts, the need for validation studies and shift in logic of providing identification evidence. This Element addresses the idea of progress in forensic authorship analysis in terms of these three issues with regard to new knowledge about the nature of authorship and methods in stylistics and stylometry. The author proposes that the focus needs to shift to validation of protocols for approaching case questions, rather than on validation of systems or general approaches.
