Thomas Nevin’s photographic reductions of large printed documents to the size of a carte-de-visite  – 54.0 mm (2.125 in) × 89 mm (3.5 in) mounted on a card sized 64 mm (2.5 in) × 100 mm (4 in) – “evoked much admiration” when reported in the press. His first noted experiment in 1870 was the replication to a pocket sized card of the Town Clerk’s poster which provided the public with information on how to interpret fire bell alarms. The second was the reduction of the front page of the Mercury a day before the Christmas Eve edition, 23rd December 1874, printed as a gift card. Although examples of these photographic reductions might be read with the naked eye, some experiments, such as those by Nevin’s more senior contemporary, Charles A. Woolley, which required viewing with a magnifying glass, would more likely be described as microform cards, using the methods of microphotography pioneered by John Benjamin Dancer (1812–1887). Dancer’s miniaturized photographs of texts in 1857 heralded the use of microphotography for the storage of large documents and records held in the archives of courts, libraries, and government departments. The reverse photographic method, enlarging microscopic material such as bacteria, is more precisely termed photomicrography. … More Thomas Nevin’s photographic reduction of large documents 1870s
