The Fingerprint Source Book was prepared as an internal reference document, drawing together all of the information held by the Home Office Centre for Applied Science and Technology (CAST) regarding internally managed experimental work on finger mark enhancement techniques. The preparation of the document was carried out in anticipation that supporting evidence would be required for validation of the techniques within the Manual of Fingerprint Development Techniques, as part of the ISO 17025 accreditation of the CAST forensic laboratories.
As CAST and police force laboratories have progressed with the ISO 17025 accreditation process, the Fingerprint Source Book has become regarded as a more widely important document. Because it provides the validation of the techniques contained within the manual, and hence the techniques used by police forces, it has become necessary for the document to be formally issued and controlled.
