The Internet Archive discovers and captures web pages through many different web crawls. At any given time several distinct crawls are running, some for months, and some every day or longer. View the web archive through the Wayback Machine.

Collection: Wide Crawl started March 2011

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 some further 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.

NC PUBLIC SCHOOL FACTS

HIGH SCHOOL GRADUATION REQUIREMENTS

North Carolina high school students are expected to meet specific course and credit requirements in order to receive a high school diploma. These requirements differ depending on when students entered ninth grade for the first time. Students should also be aware that local districts may impose additional graduation requirements. School counselors are available to answer any questions students may have about what they need to graduate.

WHAT STUDENTS STUDY

North Carolina students in kindergarten through 12th grade study English/language arts, mathematics, science, social studies, the arts, guidance, healthful living, library/media/computer skills, second languages, and workforce development subjects. The State Standard Course of Study outlines for teachers the competencies and objectives students should master.

To measure how well students are learning the curriculum, local school districts test students in grades 3 through 8 in reading and mathematics, and at grades 5 and 8 in science. All high school students take end-of-course tests in Algebra I, Algebra II, English I, U.S. History, Biology, Physical Science, and Civics and Economics. Workforce development courses also have statewide assessments through VoCATS.
