Lost Media

	Lost Media Lost media are pieces of media that are nonexistent, missing, or unavailable to the general public. The term ''lost media'' primarily encompasses visual, audio, or audiovisual media such as films, television and radio broadcasts, music, and video games. Lost artworks and lost literary works may also fit into this umbrella term, although ''lost works'' is a more common expression in these cases. Since the advent of streaming media on the Internet, use of the term ''lost media'' has concentrated on those pieces of mass media that have not surfaced on the World Wide Web or streaming services. Such media—primarily recorded onto magnetic tape in the case of television and radio broadcast masters—may be entirely lost due to the industry practice of wiping (broadcast media was often considered ephemeral and of little historical worth before the rise of home media in the late 1970s). Others are known to exist but are hard to access outside of archives such as the Library of Congress of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Media (communication) In mass communication, media are the communication outlets or tools used to store and deliver information or data. The term refers to components of the mass media communications industry, such as print media, publishing, the news media, photography, Movie theater, cinema, broadcasting (radio and television), digital media, and advertising. The development of early writing and paper enabling longer-distance communication systems such as mail, including in the Achaemenid Empire, Persian Empire (Chapar Khaneh and Angarium) and Roman Empire, can be interpreted as early forms of media. Writers such as Howard Rheingold have framed early forms of human communication, such as the Lascaux, Lascaux cave paintings and early writing, as early forms of media. Another framing of the history of media starts with the Chauvet Cave paintings and continues with other ways to carry human communication beyond the short range of voice: smoke signals, Trail blazing, trail markers, and sculpture.

picture info	Library Of Congress The Library of Congress (LOC) is the research library that officially serves the United States Congress and is the ''de facto'' national library of the United States. It is the oldest federal cultural institution in the country. The library is housed in three buildings on Capitol Hill in Washington, D.C.; it also maintains a conservation center in Culpeper, Virginia. The library's functions are overseen by the Librarian of Congress, and its buildings are maintained by the Architect of the Capitol. The Library of Congress is one of the largest libraries in the world. Its "collections are universal, not limited by subject, format, or national boundary, and include research materials from all parts of the world and in more than 470 languages." Congress moved to Washington, D.C., in 1800 after holding sessions for eleven years in the temporary national capitals in New York City and Philadelphia. In both cities, members of the U.S. Congress had access to the sizable collection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Digital Preservation In library and archival science, digital preservation is a formal endeavor to ensure that digital information of continuing value remains accessible and usable. It involves planning, resource allocation, and application of preservation methods and technologies,Day, Michael. "The long-term preservation of Web content". Web archiving (Berlin: Springer, 2006), pp. 177-199. . and it combines policies, strategies and actions to ensure access to reformatted and "born-digital" content, regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time.Evans, Mark; Carter, Laura. (December 2008). The Challenges of Digital Preservation. Presentation at the Library of Parliament, Ottawa. The Association for Library Collections and Technical Services Preservation and Reformatting Section of the American Library Association, defined digital preservation as combination of "policies, strategies an ...

	Data Preservation Data preservation is the act of conserving and maintaining both the safety and integrity of data. Preservation is done through formal activities that are governed by policies, regulations and strategies directed towards protecting and prolonging the existence and authenticity of data and its metadata. Data can be described as the elements or units in which knowledge and information is created, and metadata are the summarizing subsets of the elements of data; or the data about the data. The main goal of data preservation is to protect data from being lost or destroyed and to contribute to the reuse and progression of the data. History Most historical data collected over time has been lost or destroyed. War and natural disasters combined with the lack of materials and necessary practices to preserve and protect data has caused this. Usually, only the most important data sets were saved, such as government records and statistics, legal contracts and economic transactions. Scientific ...

picture info	Data Archaeology There are two conceptualisations of data archaeology, the technical definition and the social science definition. Data archaeology (also data archeology) in the technical sense refers to the art and science of recovering computer data encoded and/or encrypted in now obsolete media or formats. Data archaeology can also refer to recovering information from damaged electronic formats after natural disasters or human error. It entails the rescue and recovery of old data trapped in outdated, archaic or obsolete storage formats such as floppy disks, magnetic tape, punch cards and transforming/transferring that data to more usable formats. Data archaeology in the social sciences usually involves an investigation into the source and history of datasets and the construction of these datasets. It involves mapping out the entire lineage of data, its nature and characteristics, its quality and veracity and how these affect the analysis and interpretation of the dataset. The findings ...

picture info	Media Preservation Preservation of documents, pictures, recordings, digital content, etc., is a major aspect of archival science. It is also an important consideration for people who are creating time capsules, family history, historical documents, scrapbooks and family trees. Common storage media are not permanent, and there are few reliable methods of preserving documents and pictures for the future. Paper/prints (photos) Color negatives and ordinary color prints may fade away to nothing in a relatively short period if not stored and handled properly. This happens even if the negatives and prints are kept in the dark, because ambient light is not the determining factor, but heat and humidity are. The color degradation is the result of the dyes used in the color processes. Because color processing results in a less stable image than traditional black-and-white processing, black-and-white pictures from the 1920s are more likely to survive long-term than color films and photographs from after the m ...

	Media Archaeology Media archaeology or media archeology is a field that attempts to understand new and emerging media through close examination of the past, and especially through critical scrutiny of dominant progressivist narratives of popular commercial media such as film and television. Media archaeologists often evince strong interest in so-called dead media, noting that new media often revive and recirculate material and techniques of communication that had been lost, neglected, or obscured. Some media archaeologists are also concerned with the relationship between media fantasies and technological development, especially the ways in which ideas about imaginary or speculative media affect the media that actually emerge. The theories and concepts of media archaeology have been primarily elaborated by the scholars and cultural critics Thomas Elsaesser, Erkki Huhtamo, Siegfried Zielinski, and Wolfgang Ernst, taking off from earlier work by Michel Foucault on the archaeology of knowledge, Walter ...

picture info	Wiki A wiki ( ) is an online hypertext publication collaboratively edited and managed by its own audience, using a web browser. A typical wiki contains multiple pages for the subjects or scope of the project, and could be either open to the public or limited to use within an organization for maintaining its internal knowledge base. Wikis are enabled by wiki software, otherwise known as wiki engines. A wiki engine, being a form of a content management system, differs from other web-based systems such as blog software, in that the content is created without any defined owner or leader, and wikis have little inherent structure, allowing structure to emerge according to the needs of the users. Wiki engines usually allow content to be written using a simplified markup language and sometimes edited with the help of a rich-text editor. There are dozens of different wiki engines in use, both standalone and part of other software, such as bug tracking systems. Some wiki engines are ...

picture info	Audiovisual Audiovisual (AV) is electronic media possessing both a sound and a visual component, such as slide-tape presentations, films, television programs, corporate conferencing, church services, and live theater productions. Audiovisual service providers frequently offer web streaming, video conferencing, and live broadcast services. Computer-based audiovisual equipment is often used in education, with many schools and universities installing projection equipment and using interactive whiteboard technology. Components Aside from equipment installation, two significant elements of audiovisual are wiring and system control. If either of these components are faulty or missing, the system may not demonstrate optimal performance. Electrical wiring, Wiring is a skill that not only requires proper cable rating selection based on a number of factors, including distance to the main rack, frequency and fire codes, but wires should also be out of sight, behind the walls and in the ceiling, ...

picture info	Wiping Lost television broadcasts are mostly those early television programs which cannot be accounted for in studio archives (or in personal archives) usually because of deliberate destruction or neglect. Common reasons for loss A significant proportion of early television programming was never recorded in the first place. Early broadcasting in all genres was live and sometimes performed repeatedly. Due to there being no means to record the broadcast or, later, because the content itself was thought to have little monetary or historical value it was not deemed necessary to save it. In the United Kingdom, early programming was lost due to contractual demands by the actors' union to limit the rescreening of performances. Apart from Phonovision experiments by John Logie Baird, and some 280 rolls of 35mm film containing some of Paul Nipkow television station broadcasts, no recordings of transmissions from 1939 or earlier are known to exist. In 1947, Kinescopes (preserving the image on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	World Wide Web The World Wide Web (WWW), commonly known as the Web, is an information system enabling documents and other web resources to be accessed over the Internet. Documents and downloadable media are made available to the network through web servers and can be accessed by programs such as web browsers. Servers and resources on the World Wide Web are identified and located through character strings called uniform resource locators (URLs). The original and still very common document type is a web page formatted in Hypertext Markup Language (HTML). This markup language supports plain text, images, embedded video and audio contents, and scripts (short programs) that implement complex user interaction. The HTML language also supports hyperlinks (embedded URLs) which provide immediate access to other web resources. Web navigation, or web surfing, is the common practice of following such hyperlinks across multiple websites. Web applications are web pages that function as application s ...
