Microforms are any form, either films or paper, containing microreproductions[1] of documents for transmission, storage, reading, and printing. Microform images are commonly reduced about 25 times from the original document size. For special purposes, greater optical reductions may be used.
16 mm film refers to a popular, economical gauge of film used for motion pictures and non-theatrical (for instance, industrial or educational) film making. 16 mm refers to the width of the film. Other common film gauges include 8 mm and 35 mm.
35 mm film is the basic film gauge most commonly used for both still photography (see 135 film) and motion pictures, and remains relatively unchanged since its introduction in 1892 by William Dickson and Thomas Edison, using film stock supplied by George Eastman. The photographic film is cut into strips 35 millimeters (about 1 3/8 inches) wide — hence the name.[1][2] The standard negative pulldown for movies ("single-frame" format) is four perforations per frame along both edges, which makes for exactly 16 frames per foot[3] (for stills, the standard frame is eight perforations).
An airline provides air transport services for passengers or freight, generally with a recognized operating certificate or license. Airlines lease or own their aircraft with which to supply these services and may form partnerships or alliances with other airlines for mutual benefit.The American Library Association (ALA) is a non-profit organization based in the United States that promotes libraries and library education internationally. It is the oldest and largest library association in the world,[3] with more than 65,000 members.[4]
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. 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. Aperture cards have several advantages and disadvantages when compared to digital systems. Machinery exists to automatically store, retrieve, sort, duplicate, create, and digitize cards with a high level of automation. While many aperture cards still play an important role in archiving, their role is gradually being replaced by digital systems.Atherton Seidell (1878-July 26, 1961), a founder of the American Documentation Institute (predecessor of the American Society for Information Science), was a chemist and who became a strong proponent of the use of microfilm for the management of scientific information. As Peter Hirtle writes, "Through a series of seminal articles in Science in the 1930s and 1940s, Seidell established a theoretical justification for the use of microfilms as a means of facilitating scientific information exchange."[1]The British Library (BL) is the national library of the United Kingdom. It is located in London and is one of the world's largest research libraries, holding over 150 million items in all known languages and formats; books, journals, newspapers, magazines, sound and music recordings, patents, databases, maps, stamps, prints, drawings and much more. Its book collection is second only to the American Library of Congress. The Library's collections include around 25 million books,[2] along with substantial additional collection of manuscripts and historical items dating back as far as 300 BC.
