ABSTRACT
In other chapters, marks made by pens and other writing instruments, typewriters and printing processes have been considered. These provide the information carried by the document, the reason for its existence. This chapter covers indented impressions, fingerprints, damage and other marks which are incidental to the document’s intended purpose but indicate its history. In addition, other matters of interest to the examiner of questioned documents not dealt with elsewhere are discussed. These are the examination of passports, envelopes suspected of having been opened and resealed, and the sequencing of crossed lines.
