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.
Sterling is the currency in Gibraltar, and British notes and coins circulate alongside Gibraltar pounds and pence. Gibraltar notes and coins are not accepted in UK. Most businesses in Gibraltar will not accept Scottish or Northern Irish notes. Euros are accepted but with an exchange rate that may not necessarily be favourable, and change is normally given in Sterling.
UK debit cards and all major credit cards are widely accepted in Gibraltar.
