Web archiving

Preserving history of web pages

"Web archive" redirects here. For other uses, see Web archive (disambiguation).

Web archiving is the process of collecting, preserving, and providing access to material from the World Wide Web. The aim is to ensure that information is preserved in an archival format for research and the public.[1] The process of platformizing archives, digitizing historical records via interfaces patterned on social media platforms, can reshape collective memory by privileging content that aligns with social-media logic such as popularity, connectivity, and programmability.[2]

Web archivists typically employ automated web crawlers to capturing the massive amount of information on the Web. A widely known web archive service is the Wayback Machine, run by the Internet Archive.

The growing portion of human culture created and recorded on the web makes it inevitable that more and more libraries and archives will have to face the challenges of web archiving.[3] National libraries, national archives, and various consortia of organizations are also involved in archiving Web content to prevent its loss.

Commercial web archiving software and services are also available to organizations that need to archive their own web content for corporate heritage, regulatory, or legal purposes.

## History and development

[edit]

While curation and organization of the web has been prevalent since the mid- to late-1990s, one of the first large-scale web archiving projects was the Internet Archive, a non-profit organization created by Brewster Kahle in 1996.[4] The Internet Archive released its own search engine for viewing archived web content, the Wayback Machine, in 2001.[4] As of 2018, the Internet Archive was home to 40 petabytes of data.[5] The Internet Archive also developed many of its own tools for collecting and storing its data, including PetaBox for storing large amounts of data efficiently and safely, and Heritrix, a web crawler developed in conjunction with the Nordic national libraries.[4] Other projects launched around the same time included a web archiving project by the National Library of Canada, Australia's Pandora, Tasmanian web archives and Sweden's Kulturarw3.[6][7]

From 2001 to 2010,[failed verification] the International Web Archiving Workshop (IWAW) provided a platform to share experiences and exchange ideas.[8][9] The International Internet Preservation Consortium (IIPC), established in 2003, has facilitated international collaboration in developing standards and open source tools for the creation of web archives.[10]

The now-defunct Internet Memory Foundation was founded in 2004 and founded by the European Commission in order to archive the web in Europe.[4] This project developed and released many open source tools, such as "rich media capturing, temporal coherence analysis, spam assessment, and terminology evolution detection."[4] The data from the foundation is now housed by the Internet Archive, but not currently publicly accessible.[11]

Despite the fact that there is no centralized responsibility for its preservation, web content is rapidly becoming the official record. For example, in 2017, the United States Department of Justice affirmed that the government treats the President's tweets as official statements.[12]

## Methods of collection

[edit]

See also: List of Web archiving initiatives and List of web archiving file formats

Web archivists generally archive various types of web content including HTML web pages, style sheets, JavaScript, images, and video. They also archive metadata about the collected resources such as access time, MIME type, and content length. This metadata is useful in establishing authenticity and provenance of the archived collection.

### Transactional archiving

[edit]

Transactional archiving is an event-driven approach, which collects the actual transactions which take place between a web server and a web browser. It is primarily used as a means of preserving evidence of the content which was actually viewed on a particular website, on a given date. This may be particularly important for organizations which need to comply with legal or regulatory requirements for disclosing and retaining information.[13]

A transactional archiving system typically operates by intercepting every HTTP request to, and response from, the web server, filtering each response to eliminate duplicate content, and permanently storing the responses as bitstreams.

## Difficulties and limitations

[edit]

### Crawlers

[edit]

Web archives which rely on web crawling as their primary means of collecting the Web are influenced by the difficulties of web crawling:

* The robots exclusion protocol may request crawlers not access portions of a website. Some web archivists may ignore the request and crawl those portions anyway.
* Large portions of a website may be hidden in the Deep Web. For example, the results page behind a web form can lie in the Deep Web if crawlers cannot follow a link to the results page.
* Crawler traps (e.g., calendars) may cause a crawler to download an infinite number of pages, so crawlers are usually configured to limit the number of dynamic pages they crawl.
* Most of the archiving tools do not capture the page as it is. It is observed that ad banners and images are often missed while archiving.

However, it is important to note that a native format web archive, i.e., a fully browsable web archive, with working links, media, etc., is only really possible using crawler technology.

The Web is so large that crawling a significant portion of it takes a large number of technical resources. Also, the Web is changing so fast that portions of a website may suffer modifications before a crawler has even finished crawling it.

### General limitations

[edit]

Some web servers are configured to return different pages to web archiver requests than they would in response to regular browser requests. This is typically done to fool search engines into directing more user traffic to a website and is often done to avoid accountability or to provide enhanced content only to those browsers that can display it.

Not only must web archivists deal with the technical challenges of web archiving, they must also contend with intellectual property laws. Peter Lyman[14] states that "although the Web is popularly regarded as a public domain resource, it is copyrighted; thus, archivists have no legal right to copy the Web". However national libraries in some countries[15] have a legal right to copy portions of the web under an extension of a legal deposit.

Some private non-profit web archives that are made publicly accessible like WebCite, the Internet Archive or the Internet Memory Foundation allow content owners to hide or remove archived content that they do not want the public to have access to. Other web archives are only accessible from certain locations or have regulated usage. WebCite cites a recent lawsuit against Google's caching, which Google won.[16]

## Laws

[edit]

In 2017 the Financial Industry Regulatory Authority, Inc. (FINRA), a United States financial regulatory organization, released a notice stating all the businesses doing digital communications are required to keep a record. This includes website data, social media posts, and messages.[17] Some copyright laws may inhibit Web archiving. For instance, academic archiving by Sci-Hub falls outside the bounds of contemporary copyright law. The site provides enduring access to academic works including those that do not have an open access license and thereby contributes to the archival of scientific research which may otherwise be lost.[18][19]
