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.
Following the conclusion of the continental qualification tournaments for the Rio 2016 Olympic Games, for several players with aspirations of gaining places in the Menís Singles and Womenís Singles events in the Brazilian city in August, it has been a nervous time.
Now, the 22 places available by ranking are known; for Romaniaís Ovidiu Ionescu and the Slovak Republicís Barbora Balazova it is the biggest sigh of relief.
On the ITTF Olympic Games Singles Ranking published on Thursday 5th May, they are the players whose names appear in the respective Menís and Womenís lists just above the water line.
The Listing The ITTF Olympic Games Singles Ranking takes into account the players who competed in the continental tournaments but did not secure places for Rio de Janeiro.
Equally the fact that only two athletes per National Olympic Committee are eligible for each of the Menís Singles and Womenís Singles events adds a further dimension.
Conjecture Approval from the National Olympic Committees awaits and the final list could well be slightly different; consider the situation with regards to China.
Ma Long and Li Xiaoxia are the players who have secured their places in the respective Menís Singles and Womenís Singles events in Rio de Janeiro. They emerged successful at the recent ITTF-Asia Olympic Games Qualification Tournament in Hong Kong.
The National Olympic Committee has approved their participation; thus for China one place remains in each discipline. On the ITTF Olympic Games Singles Ranking, Fan Zhendong is the highest ranked male player; Liu Shiwen heads the Womenís list.
They receive the invitations to compete in the respective Menís Singles and Womenís Singles events.
Next in Line If either player is not accepted, the next in line would receive the invitation; for the men it would be Xu Xin followed by Zhang Jike, for the women, Ding Ning followed by Zhu Yuling.
Team Events Now with the 62 players, who have qualified for each of the Menís Singles and Womenís Singles events known, the selection for the 16 Menís Teams and 16 Womenís Team can take effect.
Six continental places are afforded, one for each of Africa, Asia, Europe, Latin America, North America and Oceania.
Next, for each continent, the highest ranked team in the May 2016 ITTF Olympic Team Ranking list, which has a National Olympic Committee and a total of two athletes already qualified will receive one additional athlete quota place from the Team Quota (22 places in total) to form a team of three players.
If within a given continent no National Olympic Committee has qualified two athletes, then the highest ranked team, based on the May 2016 ITTF Olympic Team Ranking list, with one athlete already qualified will receive two additional athlete quota places from the Team Quota to form a team of three players.
Clock Ticks The final list moves ever nearer; the clock ticks.
