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.
Tabb has made swift progress up the ranks since making her debut
Michaela Tabb will become the first woman to referee snooker's World Championship final next month when she takes charge of the Crucible decider.
The 41-year-old from Dunfermline has been officiating on the professional Tour since 2001.
The former Ladies European Pool champion officiated at the finals of the 2007 Welsh Open, the 2008 Masters at Wembley and this year's China Open.
"I've been chosen because of my standard of refereeing," she said.
Tabb, who made her first World Championship appearance in 2003, added: "When I started, I couldn't have imagined I'd come this far.
"At the beginning, my only ambition was to be a good referee. It was only after I'd been on the circuit for around three years, when I realised I had the ability, that I felt had the potential to get this far.
"I will be nervous and the worst time for me will be after I set the balls up before the final. After that there's a wait of about 40 minutes until the match starts. It will seem like the longest 40 minutes of my life and there will be butterflies.
"But after the first frame I'll be fine as the big occasion brings the best out of me."
The competition begins on Saturday in Sheffield with the final on 3 and 4 May.
