In THE LAYMAN’S GLOSSARY: Terms Relating to the Forensic Examination of Handwriting, Signatures and Documents , handwriting expert witness Jacqueline A. Joseph, CDE, Board Certified Examiner of Handwriting & Documents, writes:
This glossary has been designed to meet the needs of those seeking to gain the meaning of common forensic terms and to understand the jargon used during the examination of questioned handwriting and signatures…
Because it would be impracticable to include all forensic terms in a work of this size and scope, this work includes many of the common terms relating to the examination of questioned handwriting and signature examination. It does not include terms relating to laboratory equipment, ink differentiation or other methods involving aspects beyond the examination of handwriting and signatures. However, it is my intention to publish expanded editions in the future….
