![]() ![]() The year 1938 also saw another major event in the history of microfilm when University Microfilms International (UMI) was established by Eugene Power. Roll microfilm proved far more satisfactory as a storage medium than earlier methods of film information storage, such as the Photoscope, the Film-O-Graph, the Fiske-O-Scope, and filmslides. Harvard University Library was the first major institution to realize the potential of microfilm to preserve broadsheets printed on high-acid newsprint and it launched its "Foreign Newspaper Project" to preserve such ephemeral publications in 1938. This method of information storage received the sanction of the American Library Association at its annual meeting in 1936, when it officially endorsed microforms. In 1935, Kodak's Recordak division began filming and publishing The New York Times on reels of 35 millimeter microfilm, ushering in the era of newspaper preservation on film. Peters developed a method to microformat dissertations, and in 1934 the United States National Agriculture Library implemented the first microform print-on-demand service, which was quickly followed by a similar commercial concern, Science Service. Binkley, which looked closely at microform's potential to serve small print runs of academic or technical materials. īetween 19, the Library of Congress microfilmed more than three million pages of books and manuscripts in the British Library in 1929 the Social Science Research Council and the American Council of Learned Societies joined to create a Joint Committee on Materials for Research, chaired for most of its existence by Robert C. ![]() In 1928, the Eastman Kodak Company bought McCarthy's invention and began marketing check microfilming devices under its "Recordak" division. ![]() New York City banker George McCarthy was issued a patent in 1925 for his "Checkograph" machine, designed to make micrographic copies of cancelled checks for permanent storage by financial institutions. 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 dispatch was protected by being inserted in the quill, which was then attached to the tail feather. The pigeons each carried a dispatch that was tightly rolled and tied with a thread, and then attached to a tail feather of the pigeon. The prints were on photographic paper and did not exceed 40 mm, to permit insertion in a goose-quill or thin metal tube, which protected against the elements. 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. WikiProject Libraries may be able to help recruit an expert.
