The Aston Institute for Forensic Linguistics (AIFL) has made publicly available its “Forensic Linguistic Databank” (F0LD),  a permanent, controlled access online repository for forensic linguistic data, including malicious communication data, investigative interview data, and forensic evidence validation data for both speech and text.

FoLD comprises a wide range of datasets with relevance to forensic linguistics and language and law, including commercial extortion letters, investigative interviews in police and other contexts, legal documents, forum posts from far-right online groups, and comment threads from political blogs.

The intention for the databank is to not only further academic research into forensic linguistics by developing new methods and approaches but also to directly contribute to impact in assisting the delivery of justice. Therefore, research projects using this data will validate methods for forensic analysis, further the effectiveness of interviewing techniques used by British police, and help tackle internet crime and abuse on behalf of law enforcement beneficiaries, such as the National Crime Agency.

Some recent additions to FoLD are:

• The Shipman Inquiry ( the collection of all documents pertaining to the Shipman Inquiry, the trial for dr. Harold Fredrick Shipman, who was convicted at Preston Crown Court on 31 January 2000 of the murder of 15 of his patients and of one count of forging a will.
• Pledges to Harm: 8 non-realized pledges to harm, where no real-world violence was attempted, totaling 1,552 words. 6 realized pledges to harm, where real-world violence was attempted, totaling 2,638 words. 10 of the 14 were authored between 2014-2016.
