- What is the UK Web Archive?
The UK Web Archive contains UK websites that publish research, that reflect the diversity of lives, interests and activities throughout the UK, and demonstrate web innovation. This includes "grey literature" sites those that carry briefings, reports, policy statements, and other ephemeral but significant forms of information.
Contributors to the UK Web Archive seek permission from the website owner for every website it archives. This is costly and difficult (many owners simply don't respond to the request) so we have been advising the Government on the necessary regulations required to gather all in-scope UK websites automatically. The British Library and other "legal deposit libraries" have this right in principle under the Legal Deposit Libraries Act (2003) but need a further legal regulation to go ahead.
Because sites are revisited and snapshots ('instances') are taken at regular intervals, readers can see how a site evolves over time.
The archive is free to view, accessed directly from the Web itself and, since archiving began in 2004, has collected thousands of websites.
- Why is a web archive needed?
There are millions of UK websites. They are constantly changing and even disappearing. Often they contain information that is only available on the Web. Responding to the challenge of a potential "digital black hole" web archives are designed to safeguard as many of these websites as practical. The purpose of the UK Web Archive is to collect, preserve and give permanent access to key UK websites for future generations.

- Who is the UK Web Archive for?
All are welcome to use the UK Web Archive and to nominate sites that are not yet in the collections.
The UK Web Archive is designed to appeal to users across a wide spectrum of interest and knowledge: the general reader, the teacher, the journalist, the policy maker, the academic and personal researcher, and many more besides. Those represented by the sites themselves, in all the diversity of the United Kingdom, are also intended to be prime users.
Most users will find archived sites that deal with their particular area of interest or subject, and which may contain information that is no longer given on the equivalent live site. Sometimes the live site will no longer exist: in which case the UK Web Archive is likely to hold the only copy that remains. Because the Web is of such cultural importance in itself researchers of the history of the Internet will also find the UK Web Archive of great interest. Website owners themselves use the UK Web Archive to locate information misplaced from previous versions of their sites.
- How big is the archive?
Please check the Archive statistics page for up to date figures on the size of the archive.
- How frequently are sites gathered?
Typically a website is gathered at six monthly intervals, although the gather frequency varies depending on the likelihood of a change in content or the scope of a particular Special Collection.
Some websites are archived only once, for example because they are about to close and are only presenting material that will not change again.
Decisions are made on a case by case basis.

- Who are the organisations behind the UK Web Archive?
The UK Web Archive is provided by the British Library in partnership with the National Library of Wales, JISC and The Wellcome Library. In the past, The National Archive and the National Library of Scotland have also been involved. The British Library also works with the The Live Art Development Agency, The Society of Friends Library, The Women's Library at London Metropolitan University and other key institutions to build Special Collections within the UK Web Archive.
- How are websites selected?
Contributors to the UK Web Archive select websites according to their own collection development policies and areas of expertise. Selected websites are considered to be of long term research value, either in themselves or as part of a Special Collection of themed materials. Typically, archived websites publish research, reflect the diversity of lives, interests and activities throughout the UK, or demonstrate web innovation. They are chosen to represent a range of social, political, cultural, religious, scientific or economic activities. Members of the public, including website owners themselves, are welcome to nominate a website for the archive.
- Is permission asked first before a website is archived?
Contributors to the UK Web Archive seek permission from the website owner for every website it archives unless the website already states that is has given permission (for example through a Creative Commons Licence) or the contributor already has rights to the site (for example, the British Library archives its own site). Asking permission is costly and difficult (many owners simply don't respond to the request) so we have been advising the Government on the necessary regulations required to gather all in-scope UK websites automatically. The British Library and other "legal deposit libraries" have this right in principle under the Legal Deposit Libraries Act (2003) but need a further legal regulation to go ahead.
- Does Legal Deposit legislation apply to websites?
The Legal Deposit Libraries Act (2003) extended the right of the Legal Deposit Libraries to claim online publications, subject to regulations required by the Act and to be determined by the Government. The process of forming such regulations is still underway so contributors to the UK Web Archive ask permission before archiving UK sites. The UK Legal Deposit Libraries are The British Library, The National Library of Scotland, The National Library of Wales, The Bodleian Library, Oxford and Cambridge University Library. The British Library is currently preparing the technical infrastructure to support the larger scale harvesting that regulation would allow.
- Are "trivial" sites included?
Beauty and 'trivia' are in the eye of the beholder. The approach of the UK Web Archive is to take a broad view and to build as far as practicable a balanced overall collection. There will be some archived websites that divide users between those who regard them as inappropriate and those who regard them as significant aspects of contemporary life secured for future researchers.

- Does the UK Web Archive endorse websites?
No. Websites are selected from right across the legal spectrum of opinion and political range, on all sides of any particular debate. Websites in the archive also vary in the sophistication of their production values: from the basic to the equivalent of 'glossy'.
- Where is the archive held?
The UK Web Archive's are stored at the British Library. Plans are underway to store it within the British Library's Digital Library System.
- Can anyone nominate a UK website?
Yes, if you have a UK favourite and would like to suggest it for archiving, you are most welcome to nominate a website. If you are the owner of a UK website you are especially encouraged to nominate your own site: this will make the permissions process as straightforward as possible. However, please note that we reserve the right to decide whether to include a site and that for technical reasons we may not be able to archive all sites.

- Why are some archived websites absent, incomplete or display strangely?
Some websites haven't been selected yet: please nominate a website you notice isn't in the archive but you think should be. Sometimes websites have been identified already but the website owner hasn't responded to a request to archive, or (very rarely) they have refused.
Websites are gathered at a particular point in time by harvesting software and are intended to reflect as completely as possible how the website looked and behaved on the Internet at that time. An attempt is made to gather all of the objects associated with a website including html, images, PDF documents, audio and video files and other objects such as programming scripts.
However, even the state-of-the-art web crawlers used by the UK Web Archive have technical limitations and are currently unable to capture streaming media, deep web or database content requiring user input, interactive components based on programming scripts or content which requires plug-ins for rendering. This means that certain elements in some of the archived websites are not present.
Another reason some archived websites are not complete is that occasionally only one page of the site was ever intended for the archive. This may be due to the kind of permission granted for archiving or may be because the selector regarded the single page as sufficiently representing one aspect within a Special Collection.
Finally, websites often link to other websites and it is not always clear to the user that they are doing so. Unless the linked-to website has also been archived by the UK Web Archive when the user clicks on the link they will go to the "Resource Not in Archive" message.
The archive is designed to support as many browsers as possible but sometimes different browsers will give different display results: please try a different browser if you are having difficulties with display.
- How can I get my website or other intellectual property removed from the archive?
We respect intellectual property rights (IPR) and data privacy. We seek the appropriate permissions from rights holders and operate a Notice and Take-down Procedure which notifies us to take down web sites from UK Web Archive under appropriate circumstances.

- How can I protect my privacy if information about me is archived?
It's important for any person making work publicly available on the Internet to be careful with their personal information and that of others. The UK Web Archive collects web pages that are freely and openly available on the Internet. The Archive does not collect pages that require a password to access them (unless specific permission has been given), pages tagged for "robots exclusion" by their owners, pages that are only accessible when a person types into and sends a form, or pages on secure servers such as intranets.
However, if you have queries about material in the archive that you feel may infringe your privacy please contact the Archive.
- Can I link to the UK Web Archive?
Yes. Please follow the instructions given in Technical information.
- Are there other web archives?
Yes. A number of countries and organisations have developed web archives, each with their own approach and range of accessibility. Please see links for more information.
- When will my site appear in the archive?
As soon as practically possible, but please bear with us because we need to spread our archiving schedules to maintain efficiency overall. Websites also need to go through a quality assurance process once they have been harvested: this is the checking that makes sure all archivable elements of the site have transferred properly. Contact the Archive if you have a query about your site.
