Web wide crawl with initial seedlist and crawler configuration from March 2011. This uses the new HQ software for distributed crawling by Kenji Nagahashi.
What?s in the data set:
Crawl start date: 09 March, 2011
Crawl end date: 23 December, 2011
Number of captures: 2,713,676,341
Number of unique URLs: 2,273,840,159
Number of hosts: 29,032,069
The seed list for this crawl was a list of Alexa?s top 1 million web sites, retrieved close to the crawl start date. We used Heritrix (3.1.1-SNAPSHOT) crawler software and respected robots.txt directives. The scope of the crawl was not limited except for a few manually excluded sites.
However this was a somewhat experimental crawl for us, as we were using newly minted software to feed URLs to the crawlers, and we know there were some operational issues with it. For example, in many cases we may not have crawled all of the embedded and linked objects in a page since the URLs for these resources were added into queues that quickly grew bigger than the intended size of the crawl (and therefore we never got to them). We also included repeated crawls of some Argentinian government sites, so looking at results by country will be somewhat skewed.
We have made many changes to how we do these wide crawls since this particular example, but we wanted to make the data available ?warts and all? for people to experiment with. We have also done somefurther analysis of the content.
If you would like access to this set of crawl data, please contact us at info at archive dot org and let us know who you are and what you?re hoping to do with it. We may not be able to say ?yes? to all requests, since we?re just figuring out whether this is a good idea, but everyone will be considered.


Nomination to the Prize in Economic Sciences is by invitation only. The names of the nominees and other information about the nominations cannot be revealed until 50 years later.
The Royal Swedish Academy of Sciences is responsible for the choice of the Laureates in Economic Sciences from among the candidates recommended by the Economic Sciences Prize Committee. The Committee is the working body that screens the nominations and selects the final candidates for the Economic Sciences Prize. It is composed of five members, but for many years the Committee has included adjunct members with the same voting rights as members.
The candidates eligible for the Prize in Economic Sciences are those nominated by qualified persons who have received an invitation from the Economic Sciences Prize Committee to submit names for consideration. No one can nominate himself or herself.

Below is a brief description of the process involved in choosing the Laureates in Economic Sciences.
September –Nomination forms are sent out. The Economic Sciences Prize Committee sends out confidential forms to around 3,000 individuals – selected professors at universities around the world, Laureates in Economic Sciences, and members of the Royal Swedish Academy of Sciences, among others.
February –Deadline for submission. The completed forms must reach the Economic Sciences Prize Committee no later than January 31 of the following year. The Committee screens the nominations and selects the preliminary candidates. About 250-350 names are nominated as the same names are often submitted by several nominators.
March-May – Consultation with experts. The Economic Sciences Prize Committee sends the names of the preliminary candidatesto specially appointed experts for their assessment of the candidates' work.
June-August–Writing of the report. The Economic Sciences Prize Committee puts together the report with recommendationsto be submitted to the Academy. The report is signed by all membersof the Committee.
September –Committee submits recommendations. The Economic Sciences Prize Committee submits its report with recommendations on the final candidates to the members of the Academy. The report is discussed at two meetings of the Economic Sciences Section of the Academy.
October –Economic Sciences Laureates are chosen. In early October, the Academy of Sciences selects the Laureates in Economic Sciences through a majority vote. The decision is final and without appeal. The names of the Laureates in Economic Sciences are then announced.
December –Economic Sciences Laureates receive theirprize. The Nobel Prize Award Ceremony takes place on10 December in Stockholm, where the Nobel Laureates receivetheir Nobel Prize, which consists of a Nobel Medal and Diploma,and a document confirming the prize amount.
The statutes of the Nobel Foundation restrict disclosure of informationabout the nominations, whether publicly or privately, for 50 years.The restriction concerns the nominees and nominators, as well as investigationsand opinions related to the award of a prize.
The right to submit proposals for the award of The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel shall, by statute, be enjoyed by:
| 1. | Swedish and foreign members of the Royal Swedish Academy of Sciences; |
| 2. | Members of the Prize Committee for the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel; |
| 3. | Persons who have been awarded the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel; |
| 4. | Permanent professors in relevant subjects at the universities and colleges in Sweden, Denmark, Finland, Iceland and Norway; |
| 5. | Holders of corresponding chairs in at least six universities or colleges, selected for the relevant year by the Academy of Sciences with a view to ensuring the appropriate distribution between different countries and their seats of learning; and |
| 6. | Other scientists from whom the Academy may see fit to invite proposals. |
Decisions as to the selection of teachers and scientists referred to in paragraphs 5 and 6 above shall be taken each year before the end of the month of September.
The Prize in Economic Sciences is not a Nobel Prize. In 1968, Sveriges Riksbank (Sweden's central bank) instituted "The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel", and it has since been awarded by the Royal Swedish Academy of Sciences, Stockholm.
