This first edition is a must have for the professional Questioned Document Examner. Excellent details in pen, ink, paper, indented writing Forensice Document Examination. Some methods of ink and pen identification qre not even covered in most Forensic Questioned Document Books, Not in the detail covered here. How do you know if an envelope has been steamed opened and reglued? What methods of page substitution are not covered in other tests? How can you quickly identify, beyond watermarks, if a page may not be consistent with others in a corporate agreement? Mr Ellen is truly a master Forensic Document Examiner. In my opinion he is the modern day version of Albert Osborn. My Osborn's Questioned Documents was the first complete book on Questioned Document Examination. It is dated now but Mr. Ellen's book covers it all. A great book. A must have for the 21st century.
The 1st and 2nd editon should not be confused with the 3rd edition. The 1st and 2nd edition give great technical detail as to methodology in use of Forensic Equipment, VSC-1, ESDA, IR/UV, ink and paper analysis. The 3rd edition answers methodology in visual examination as to methods of construction,disquised writing, simulations,significance of similarities and differences. The 3rd edition is more general than the previous editions but an excellent resource for the Forensic Questioned Document Examiner in training and as a refresher for the seasoned Forensic Questioned Document Examiner. It is also a must have for the Forensic Questioned Document Examiner Library.
