Microfilm
Microforms are scaled-down reproductions of documents, typically either photographic film, films or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or of the original document size. For special purposes, greater optical reductions may be used. Three formats are common: microfilm (reels), microfiche (flat sheets), and aperture cards. Microcards, also known as "micro-opaques", a format no longer produced, were similar to microfiche, but printed on cardboard rather than photographic film. History Using the daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs, in 1839. He achieved a reduction ratio of 160:1. 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. The idea that microphotogr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aperture Card
An aperture card is a type of punched card with a cut-out window into which a chip of microfilm is mounted. Such a card is used for archiving or for making multiple inexpensive copies of a document for ease of distribution. The card is typically punched with machine-readable metadata associated with the microfilm image, and printed across the top of the card for visual identification; it may also be punched by hand in the form of an edge-notched card. The microfilm chip is most commonly 35mm in height, and contains an optically reduced image, usually of some type of reference document, such as an engineering drawing, that is the focus of the archiving process. Machinery exists to automatically store, retrieve, sort, duplicate, create, and digitize cards with a high level of automation. Aperture cards have several advantages and disadvantages when compared to digital systems. While many aperture cards still play an important role in archiving, their role is gradually being re ...

Eugene Power
Eugene Barnum Power (June 4, 1905 – December 6, 1993) was an American entrepreneur, philanthropist, founder of the modern microfilm industry, and pioneer in the use of microfilm for the reproduction of scholarly publications. Life and career Born in Traverse City, Michigan, on June 4, 1905, Power received his BA degree in 1927 and his MBA in 1930, both from the University of Michigan. He married Sadye L. Harwick in 1929, and the couple had one son, Philip. His wife died in 1991. During World War II, Power directed the microfilming of thousands of rare books and other printed materials in British libraries. He paid the library a minimal fee per exposure and then took the film to the United States where he sold copies to US libraries. The idea was both a clever business arrangement and a benefit to American scholars, who lacked access to European library collections. It was also an inventive form of preservation in light of wartime threats to libraries. Queen Elizabeth II kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pigeon Post
Pigeon post is the use of homing pigeons to carry messages. Pigeons are effective as messengers due to their natural homing abilities. The pigeons are transported to a destination in cages, where they are attached with messages, then the pigeon naturally flies back to its home where the recipient could read the message. They have been used in many places around the world. Pigeons have also been used to great effect in military situations, and are in this case referred to as war pigeons. Early history As a method of communication, it is likely as old as the ancient Persians, from whom the art of training the birds probably came. The Romans used pigeon messengers to aid their military over 2000 years ago. Frontinus said that Julius Caesar used pigeons as messengers in his conquest of Gaul. The Greeks conveyed the names of the victors at the Olympic Games to their various cities by this means. Naval chaplain Henry Teonge (c. 1620–1690) describes in his diary a regular pigeon ...

Robert Goldschmidt
Robert B. Goldschmidt (1877–1935) was a Belgian chemist, physicist, and engineer who first proposed the idea of standardized microfiche (microfilm). Goldschmidt was a polymath who also made advances in aviation and radio, among other fields. In 1913 he constructed a major radio facility at Laeken, Belgium, where in 1914 he and Raymond Braillard inaugurated Europe's first regular radio concert broadcasts. He was also a participant in the first and second international Solvay Conferences reviewing outstanding issues in chemistry and physics. Education and academic career Educated in Brussels and Berlin, Goldschmidt was a professor of chemistry at the University of Brussels for some thirty years. Career Microfilm In the first years of the twentieth century, he worked with Paul Otlet on the creation of microfilm, then known as "microphotographs. In 1906, he and Otlet proposed what they called the "livre microphotographique," which they considered to be a cheaper, more space-s ...

Paul Otlet
Paul Marie Ghislain Otlet (; ; 23 August 1868 – 10 December 1944) was a Belgian author, entrepreneur, lawyer and peace activist; predicting the arrival of the internet before World War II, he is among those considered to be the father of information science, a field he called "documentation". Otlet created the Universal Decimal Classification, which would later become a faceted classification. Otlet was responsible for the development of an early information retrieval tool, the "" (RBU) which utilized 3x5 inch index cards, used commonly in library catalogs around the world (now largely displaced by the advent of the online public access catalog (OPAC)). Otlet wrote numerous essays on how to collect and organize the world's knowledge, culminating in two books, the ' (1934) and ' (1935). In 1907, following a huge international conference, Otlet and Henri La Fontaine created the Central Office of International Associations, which was renamed to the Union of International Ass ...
