This page in a nutshell: The preservation or survivability of the world's knowledge is at stake. Contribute it to Wikipedia before it's too late.

Practically every day, distinct forms of knowledge are lost forever and no copies are available. When a natural disaster hits a region or a war breaks out; libraries, archives, museums, monuments and other artifacts of heritage, valuable buildings, incunabula and unique objects are destroyed or face the threat of destruction. These events usually remove pieces of human knowledge and sometimes entire cultures.

There are plenty of examples of permanent loss of knowledge before Wikipedia's existence. The following is a non-exhaustive list.^[1]

• The Libraries of Alexandria, House of Wisdom and Constantinople are among many great libraries of the ancient world to have been destroyed. As well, many ancient Chinese encyclopedias are partially or completely lost to history.
• The medieval archives of Gozo were destroyed during the Ottoman invasion of 1551.^[2]
• Diego de Landa's burning of the Maya codices in 1562. Only four are known to have survived. Most knowledge of Maya history is thus lost.
• The Beeldenstorm that spread through the Low countries in 1566 in which many statues and religious artifacts of the Catholic Church were destroyed by iconoclasts.
• A fire destroyed more than 500 paintings located in Royal Alcázar of Madrid on Christmas Eve 1734. Other works, such as Las Meninas by Velázquez, were saved.
• The 1836 U.S. Patent Office fire irretrievably destroyed most of the U.S. patent documents collected up to that time.

• Astorage vault fire in 1937 destroyed all the original negatives of Fox Film Corporation's pre-1935 movies.^[6] Furthermore, the vast majority of the silent films produced in the late 19th and early 20th centuries are considered lost. According to a September 2013 report published by the United States Library of Congress, some 70 per cent of American silent feature films fall into this category.^[7]
• Hundreds of libraries and archives were destroyed and their contents lost during World War II.^[1][8][9]

• More than 6,000 Tibetan monasteries were destroyed during the Cultural Revolution, along with unique statues, tapestries and manuscripts.^[11]
• The National and University Library of Bosnia and Herzegovina was shelled and burnt to the ground, along with thousands of irreplaceable texts, in the Siege of Sarajevo in 1992 during the Bosnian War.^[12]
• Some of the original Apollo 11 moon landing tapes in high quality have been recorded over and lost.^[13] But all the data was copied as archived in several locations at the time.^[14]
• In June 1981, during the Sri Lankan Civil War, the Jaffna Public Library was burntbySinhalese Buddhist mobs, destroying over 97,000 rare books and manuscripts in the process.^[15]
• During the Romanian Revolution of 1989, a fire was started in the Central University Library of Bucharest and over 500,000 books, along with 3,700 manuscripts, were burnt.^[16]

• Islamic State of Iraq and the Levant (ISIL) damaged Mosul Museum artifacts, Mosul Public Library books and other cultural heritage sites like the ancient temples of Baalshamin and Bel.^[34]

Today, many of the world's languages are endangered or nearly extinct.^[52][53] In some cases where parents have stopped teaching an endangered language to their children, the language is understood by only a few elderly speakers. The Rosetta Project is a global collaboration of language specialists and native speakers working to build a publicly accessible digital library of material on the nearly 7,000 known human languages.^[54]

Furthermore, hundreds of websites are closed every day on the Internet; the average life of a web page is only 77 days.^[55] Those websites work in many cases as references. Projects like the Internet ArchiveorWebCitation and volunteer groups like Archive Team^[56] save copies of some of them, but many others are lost forever. This issue may affect Wikimedia projects too, and mirrors are needed to assure long-term preservation of the data.

Wikipedia and its sister projects can—and must—save all these forms of knowledge, through creating articles, uploading images and recordings to Wikimedia Commons, preserving languages in Wiktionary and transcribing books into Wikisource. Events like Wiki Loves Monuments may help to immortalize monuments around the world before they are damaged or destroyed.^[57]
