In the 1920s microfilm began to be used in a commercial setting. In 1925, the team spoke of a massive library where each volume existed as master negatives and positives, and where items were printed on demand for interested patrons. Otlet's overarching goal was to create a World Center Library of Juridical, Social and Cultural Documentation, and he saw microfiche as a way to offer a stable and durable format that was inexpensive, easy to use, easy to reproduce, and extremely compact. In 1906, Paul Otlet and Robert Goldschmidt proposed the livre microphotographique as a way to alleviate the cost and space limitations imposed by the codex format. He proposed that up to 150,000,000 words could be made to fit in a square inch, and that a one-foot cube could contain 1.5 million volumes. Fessenden suggested microforms were a compact solution to engineers' unwieldy but frequently consulted materials. The developments in microphotography continued through the next decades, but it was not until the turn of the century that its potential for practical usage was applied more broadly.
The prints were on photographic paper and did not exceed 40 mm, to permit insertion in the pigeon's quill. The chemist Charles-Louis Barreswil proposed the application of photographic methods with prints of a reduced size. Ī pigeon post was in operation while Paris was besieged during the Franco-Prussian War of 1870–1871. He called it "the most remarkable discovery of modern times", and argued in his official report for using microphotography to preserve documents. Both men attended the 1851 Great Exhibition in London, where the exhibit on photography greatly influenced Glaisher. Microphotography was first suggested as a document preservation method in 1851 by the astronomer James Glaisher, and in 1853 by John Herschel, another astronomer. The idea that microphotography could be no more than a novelty was an opinion shared in the 1858 Dictionary of Photography, which called the process "somewhat trifling and childish". Dancer refined his reduction procedures with Frederick Scott Archer's wet collodion process, developed in 1850–51, but he dismissed his decades-long work on microphotographs as a personal hobby and did not document his procedures.
Using the daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs, in 1839.
