Diferenzas entre revisións de «Wikipedia:Ligazóns mortas»

===Arquivos de internet===
Os servizos de arquivo web son moi útiles para procurar versións arquivadas das páxinas webs. De atopar unha versión arquivada dunha ligazón morta, debe comprobarse tamén que este arquivo sigue apoiando a información incorporada no artigo á que acompaña como referencia. Tamén pode ser útil comprobar a data de acceso indicada na referencia ou o historial do artigo para confirmar cando foi incorporada a ligazón na referencia e confirmar que a versión arquivada concorda co material do artigo.
Check for archived versions of the page in the [[Web archiving|archiving services]]. If you find an archived version of the dead link, double-check to make sure that citation still supports the article text. It is also a good idea to consult the access date of the citation (if it was specified, or a history search for when it was added) to see how contemporaneous this archived version is to the link when it was cited.
Algúns dos servizos de arquivo web fiables máis empregados son:
The following archiving services are considered to be reliable:
*[[Wayback Machine]] at: https://archive.org/web/
*[[Internet Archive]] at: https://archive.org/
*[[WebCite]] at: http://www.webcitation.org/query
*[[UK Government Web Archive]] at: http://webarchive.nationalarchives.gov.uk/
Na maioría de modelos de citas os arquivos das ligazóns indícanse nos parámetros {{para|url-arquivo}}, {{para|data-arquivo}} e {{para|urlmorta}}. A ligazón primaria substitúese automaticamente pola arquivada cando se indica o valor {{para|urlmorta|si}}, mantendo a ligazón orixinal como referencia.
The [http://www.webarchive.org.uk/mementos/search Mementos interface] allows you to search multiple [[Web archiving|archiving services]] for archived versions of some pages with a single request using the [[Memento Project|Memento]] protocol. Unfortunately, the Mementos webpage interface removes any [[Query string|parameters]] which are included with the URL. If the URL contains a "?" it is unlikely to work properly when entered manually without changes. When entering the URL into the Mementos interface manually, the most common [[Percent-encoding|change needed]] is to change "?" to "%3F". While making only this change will not be sufficient in all cases, it will work most of the time. The bookmarklet in the table below will properly [[Percent-encoding|encode]] URLs such that searches will work. Mementos looks like it is, or at least will be, very convenient. However, if archives are not found at Mementos, it should not be the only site checked. Mementos can sometimes return no results when archives exist at sites which it normally includes. An example of this is trying to find archives of [[Battle of the Atlantic]]. {{As of|April 2014}}, Archive.org reports it has 63 or 64 archives ([https://web.archive.org/web/*/https://en.wikipedia.org/wiki/Battle_of_the_Atlantic https], [https://web.archive.org/web/query?type=urlquery&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FBattle_of_the_Atlantic&Submit=BROWSE+HISTORY http]). Mementos reports ''0 archives'' ([http://www.webarchive.org.uk/mementos/search/https://en.wikipedia.org/wiki/Battle_of_the_Atlantic https], [http://www.webarchive.org.uk/mementos/search/http://en.wikipedia.org/wiki/Battle_of_the_Atlantic http]). Mementos usually finds archives at Archive.org, but sometimes Mementos does not even when archives exist. If you try Mementos first, don't assume that there really are no archives if Mementos reports that there are none.
There are [[List of Web archiving initiatives|many Internet archive projects]] in existence.
When multiple archive dates are available, try to use the one that is most likely to be the contents of the page seen by the editor who entered the reference on the {{para|accessdate}}. If that parameter is not specified, a [http://wikipedia.ramselehof.de/wikiblame.php?lang=en search of the article's revision history] can be performed to determine when the link was added to the article.
View the archive to verify that it contains valid page information. Sometimes archives are actually archives of the fact that the link is dead, or that the archiving failed. If this is the case, try using an archive from a different date. Usually dates closer to the time the link was placed in the Wikipedia page, or earlier, are more likely to show valid information. Different archiving sites should also be tried.
For most citation templates, archives are entered using the {{para|archiveurl}}, {{para|archivedate}} and {{para|deadurl}} parameters. The primary link is automatically switched to the archive when {{para|deadurl|yes}}. This retains the original link location for reference.
