Assembled in Early Photography Books are seventy selected manuals, histories, catalogs, reminiscences, and yearbooks covering virtually all aspects of early photography. All but ten date from the 19th century, and the remainder are historical treatments or early 20th-century studies of optics and new products. The collection includes Louis Daguerre's own technical manual of 1839 and two books by Sir David Brewster on optics and the kaleidoscope that predate Daguerre, as well as twenty-two catalogs that date between 1873 and 1925 from nine different firms. They document the rapid spread of the new art and science in terms of the developing industry. Scholars and students will find every phase of photography's early history treated in some part of this wide-ranging collection.
