Web archiving is the process of collecting portions of the World Wide Web to ensure the information is preserved in an archive for future researchers, historians, and the public.[1] Web archivists typically employ web crawlers for automated capture due to the massive size and amount of information on the Web. The largest web archiving organization based on a bulk crawling approach is the Internet Archive which strives to maintain an archive of the entire Web. The International Web Archiving Workshop (IWAW), begun in 2001, has provided a platform to share experiences and exchange ideas. The later founding of the International Internet Preservation Consortium (IIPC), in 2003, has greatly facilitated international collaboration in developing standards and open source tools for the creation of web archives. These developments, and the growing portion of human culture created and recorded on the web, combine to make it inevitable that more and more libraries and archives will have to face the challenges of web archiving. National libraries, national archives and various consortia of organizations are also involved in archiving culturally important Web content. Commercial web archiving software and services are also available to organizations who need to archive their own web content for corporate heritage, regulatory, or legal purposes.
