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.
Content crawled via the Wayback Machine Live Proxy mostly by the Save Page Now feature on web.archive.org.
Liveweb proxy is a component of Internet Archive’s wayback machine project. The liveweb proxy captures the content of a web page in real time, archives it into a ARC or WARC file and returns the ARC/WARC record back to the wayback machine to process. The recorded ARC/WARC file becomes part of the wayback machine in due course of time.

Welcome to Wikipedia!Almost every page can be edited by anyone, and millions of us already do.
This page takes you through a set of tutorials aimed at complete newcomers interested in contributing. It covers all the basics needed to navigate, comment on, and contribute to Wikipedia articles. There are two methods of editing: the VisualEditor, and Wiki markup. Each tutorial takes only about 10 minutes, so you could become a proficient 'Wikipedian' in under an hour!
Wiki Markup is the primary editor. It shows the underlying page content, and works like a plain text file. Links and other items are edited using simple code like this: [[Earth]].
VisualEditor is a secondary editing interface. It hides the underlying markup, and works more like a word processor. Links and other items are edited using a toolbar or popup interfaces.
