Perma.cc
Perma.cc is a web archiving service for legal and academic citations founded by the Harvard Library Innovation Lab in 2013. Concept Perma.cc was created in response to studies showing high incidences of link rot in both academic publications and judicial opinions. By archiving copies of linked resources, and providing them with a permanent URL, perma.cc is intended to provide longer-term verifiability and context for academic literature and caselaw. Perma.cc is administered by a network of academic and government libraries. In 2016, Harvard received a $700,000 grant from the Institute for Museum and Library Services to expand development of perma.cc. Design Perma.cc initiates page saves by user request only, it does not crawl the web and save pages like the Wayback Machine. A user account is required to save a page. Its target audience are organizations such as libraries, academic journals, law courts and school faculty. It provides support for organizational membership and adm ...

Link Rot
Link rot (also called link death, link breaking, or reference rot) is the phenomenon of hyperlinks tending over time to cease to point to their originally targeted file, web page, or server due to that resource being relocated to a new address or becoming permanently unavailable. A link that no longer points to its target, often called a ''broken'' or ''dead'' link (or sometimes ''orphan'' link), is a specific form of dangling pointer. The rate of link rot is a subject of study and research due to its significance to the internet's ability to preserve information. Estimates of that rate vary dramatically between studies. Prevalence A number of studies have examined the prevalence of link rot within the World Wide Web, in academic literature that uses URLs to cite web content, and within digital libraries. A 2003 study found that on the Web, about one link out of every 200 broke each week, suggesting a half-life of 138 weeks. This rate was largely confirmed by a 2016–2017 st ...

WebCite
WebCite was an on-demand archive site, designed to digitally preserve scientific and educationally important material on the web by taking snapshots of Internet contents as they existed at the time when a blogger or a scholar cited or quoted from it. The preservation service enabled verifiability of claims supported by the cited sources even when the original web pages are being revised, removed, or disappear for other reasons, an effect known as link rot. Service features WebCite allowed for preservation of all types of web content, including HTML web pages, PDF files, style sheets, JavaScript and digital images. It also archived metadata about the collected resources such as access time, MIME type, and content length. WebCite was a non-profit consortium supported by publishers and editors, and it could be used by individuals without charge. It was one of the first services to offer on-demand archiving of pages, a feature later adopted by many other archiving service ...

Web Archiving
Web archiving is the process of collecting portions of the World Wide Web to ensure the information is preserved in an archive for future researchers, historians, and the public. Web archivists typically employ web crawlers for automated capture due to the massive size and amount of information on the Web. The largest web archiving organization based on a bulk crawling approach is the Wayback Machine, which strives to maintain an archive of the entire Web. The growing portion of human culture created and recorded on the web makes it inevitable that more and more libraries and archives will have to face the challenges of web archiving. National libraries, national archives and various consortia of organizations are also involved in archiving culturally important Web content. Commercial web archiving software and services are also available to organizations who need to archive their own web content for corporate heritage, regulatory, or legal purposes.

Caselaw
Case law, also used interchangeably with common law, is Legal system, law that is based on precedents, that is the Judiciary, judicial decisions from previous cases, rather than law based on constitutions, statutes, or regulations. Case law uses the detailed facts of a legal case that have been resolved by courts or similar tribunals. These past decisions are called "case law", or precedent. ''Stare decisis''—a Latin phrase meaning "let the decision stand"—is the principle by which judges are bound to such past decisions, drawing on established judicial authority to formulate their positions. These judicial interpretations are distinguished from statutory law, which are codes enacted by Legislature, legislative bodies, and regulatory law, which are established by executive agencies based on statutes. In some jurisdictions, case law can be applied to ongoing adjudication; for example, criminal proceedings or family law. In common law#Disambiguate civil law, common law countrie ...

Wayback Machine
The Wayback Machine is a digital archive of the World Wide Web founded by the Internet Archive, a nonprofit based in San Francisco, California. Created in 1996 and launched to the public in 2001, it allows the user to go "back in time" and see how websites looked in the past. Its founders, Brewster Kahle and Bruce Gilliat, developed the Wayback Machine to provide "universal access to all knowledge" by preserving archived copies of defunct web pages. Launched on May 10, 1996, the Wayback Machine had more than 38.2 million records at the end of 2009. , the Wayback Machine had saved more than 760 billion web pages. More than 350 million web pages are added daily. History The Wayback Machine began archiving cached web pages in 1996. One of the earliest known pages was saved on May 10, 1996, at 2:08p.m. Internet Archive founders Brewster Kahle and Bruce Gilliat launched the Wayback Machine in San Francisco, California, in October 2001, primarily to address the problem of web co ...

Web ARChive
The Web ARChive (WARC) archive format specifies a method for combining multiple digital resources into an aggregate archive file together with related information. The WARC format is a revision of the Internet Archive's ARC_IA File Format that has traditionally been used to store " web crawls" as sequences of content blocks harvested from the World Wide Web. The WARC format generalizes the older format to better support the harvesting, access, and exchange needs of archiving organizations. Besides the primary content currently recorded, the revision accommodates related secondary content, such as assigned metadata, abbreviated duplicate detection events, and later-date transformations. The WARC format is inspired by HTTP/1.0 streams, with a similar header and the use of CRLFs as delimiters, making it very conducive to crawler implementations. First specified in 2008, WARC is now recognised by most national library systems as the standard to follow for web archiving. Software * ...

Portable Network Graphics
Portable Network Graphics (PNG, officially pronounced , colloquially pronounced ) is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) — unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF". PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics; therefore non-RGB color spaces such as CMYK are not supported. A PNG file contains a single image in an extensible structure of ''chunks'', encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. PNG files use the file extension PNG or png and hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memento Project
Memento is a United States ''National Digital Information Infrastructure and Preservation Program (NDIIPP)''–funded project aimed at making Web-archived content more readily discoverable and accessible to the public. Technical description Memento is defined in RFC 7089 as an implementation of the time dimension of content negotiation, as defined by Tim Berners Lee Sir Timothy John Berners-Lee (born 8 June 1955), also known as TimBL, is an English computer scientist best known as the inventor of the World Wide Web. He is a Professorial Fellow of Computer Science at the University of Oxford and a profes ... in 1996. HTTP accomplishes negotiation of content via headers. The table below shows the different headers available for HTTP that allow clients and servers to find the content that the user desires. To understand Memento fully, one must realize that the header provided by HTTP does not necessarily reflect when a particular version of a web page came into exis ...
