These crawls are part of an effort to archive pages as they are created and archive the pages that they refer to. That way, as the pages that are referenced are changed or taken from the web, a link to the version that was live when the page was written will be preserved.
Then the Internet Archive hopes that references to these archived pages will be put in place of a link that would be otherwise be broken, or a companion link to allow people to see what was originally intended by a page's authors.
This is a collection of web page captures from links added to, or changed on, Wikipedia pages. The idea is to bring a reliability to Wikipedia outlinks so that if the pages referenced by Wikipedia articles are changed, or go away, a reader can permanently find what was originally referred to.
The boundaries shown on the maps above are approximate and are intended
only to portray the locations of named features and their rough extents. Get help using the map above.
Changes in the control network drop down are not reflected in the feature boundaries in the map above. Only the
primary control network feature boundaries (in green) are displayed on the map.
