Bibliotics; or, The study of documents; determination of the individual character of handwriting and detection of fraud and forgery. New methods of research
Frazer's 1901 Bibliotics, published in Philadelphia by Lippincott, is a forensic manual by the Philadelphia chemist Persifor Frazer on identifying individual handwriting and detecting forgery through new research methods. The pictures are photomicrographs of ink crossings where one stroke overlies another, showing the ink lines in close-up grain and edge detail, with a single fibrous ink stroke in the last image, useful to a designer for scientific or forensic reference imagery.
