Stop Online Piracy ActThe Stop Online Piracy Act (SOPA) was a controversial proposed United States congressional bill to expand the ability of U.S. law enforcement to combat online copyright infringement and online trafficking in counterfeit goods. Introduced on October 26, 2011, by Representative Lamar Smith (R-TX), provisions included the requesting of court orders to bar advertising networks and payment facilities from conducting business with infringing websites, and search engines from linking to the websites, and court orders requiring Internet service providers to block access to the websites.
Link rotLink 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 , 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, dead, or orphaned 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.
LibriVoxLibriVox is a group of worldwide volunteers who read and record public domain texts, creating free public domain audiobooks for download from their website and other digital library hosting sites on the internet. It was founded in 2005 by Hugh McGuire to provide "Acoustical liberation of books in the public domain" and the LibriVox objective is "To make all books in the public domain available, for free, in audio format on the internet". On 6 August 2016, the completed projects numbered 10,000, and on 14 February 2021 there were 15,000 completed projects.
WebCiteWebCite is 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. The site no longer accepts new archive requests; old archive snapshots can still be viewed.
Wikimedia CommonsWikimedia Commons (or simply Commons) is a media repository of free-to-use images, sounds, videos and other media. It is a project of the Wikimedia Foundation. Files from Wikimedia Commons can be used across all of the Wikimedia projects in all languages, including Wikipedia, Wikivoyage, Wikisource, Wikiquote, Wiktionary, Wikinews, Wikibooks, and Wikispecies, or downloaded for offsite use. As of February 2023, the repository contains over 90 million free-to-use media files, managed and editable by registered volunteers.
Universal libraryA universal library is a library with universal collections. This may be expressed in terms of it containing all existing information, useful information, all books, all works (regardless of format) or even all possible works. This ideal, although unrealizable, has influenced and continues to influence librarians and others and be a goal which is aspired to. Universal libraries are often assumed to have a complete set of useful features (such as finding aids, translation tools, alternative formats, etc.).
WikisourceWikisource is an online digital library of free-content textual sources on a wiki, operated by the Wikimedia Foundation. Wikisource is the name of the project as a whole and the name for each instance of that project (each instance usually representing a different language); multiple Wikisources make up the overall project of Wikisource. The project's aim is to host all forms of free text, in many languages, and translations.
