  3. 3. www.bl.uk 3 Before (6 April 2013) • Selective archiving of websites that – reflect the diversity of lives, interests and activities throughout the UK – contain research value or are of research interest – feature political, cultural, social and economic events of national interest – demonstrate innovative use of the web – Also prioritise websites at risk and web-only content • Permission based – Permission to archive, to provide online access and to preserve. Also ask or 3rd party rights clearance – 30% success rate, 5% explicit refusal (mostly due to 3rd party rights) • Online access through UK Web Archive
  4. 4. www.bl.uk 4 Toolset • Selection and Permission Tool – selection and permission management – Integrated with the Web Curator Tool • Web Curator Tool – Job scheduling – Metadata – Access control – Harvesting (uses Heritirx) – QA • Indexing and SIP generation – scripts and SOLR (for full-text index) • Wayback – rendering tool for WARCs • UK Web Archive – web-based end user interface

  9. 9. www.bl.uk 9 Analytical access • Shift of focus from the level of single webpages or websites to the entire web archive collection. • Use web archives as datasets, access to metadata and knowledge about websites • Support survey, annotation, contextualisation and visualisation • Allows discovery of patterns, trends and relationships in inter-linked web pages • Helps addresses a number of challenging issues – Scalability – Accessibility of individual websites – Components missed by crawlers
  10. 10. www.bl.uk 10 After (6 April 2013) • Government introduced Non-print Legal Deposit Regulations 2013 • Apply to material published digitally and online, including articles books, and websites. • 6 UK Legal Deposit Libraries • Deposited content accessible “on library premises controlled by the deposit library” – after 7 days of collection or deposit – Single concurrent access – Catalogue records allowed to be searchable online – Digital copying not permitted
  11. 11. www.bl.uk 11 Legal Deposit of UK websites • In scope – Sites that use a .uk or other UK geographic top-level domain – where part of the publishing process takes place in the UK; • Will not archive – sites concerning film and recorded sound where the audio-visual content predominates – private intranets and emails • Over 10 million .uk registered domains – 4th TLD after .com, .de and .net – UK organisations also use non .uk domain names (eg .com or .org) – scale unknown

  13. 13. www.bl.uk 13 Access strategy • Deposited content cannot be accessed outside the reading rooms. • Online access can be provided to metadata and selected content to showcase the Legal Deposit web archive of the UK – Bibliographic metadata – Analysis and visualisation of aggregated content – Statistical and contextual data – Copy of deposited content with direct permission • For sites from outside the UK, permission both to harvest and for public access will be required
  14. 14. www.bl.uk 14 Before and after: what has changed • Everything! BEFORE AFTER Scale 14,000 4 – 5 million Purpose Advocacy, demonstrating benefits Legal Deposit Workflow (and tools) Selection prior to harvesting Selection / curation can happen post harvesting Permission to archive Required Can collect in-scope material without permission Access Online Reading rooms only (unless with direct permission for online access) Nature of QA Quality control leading to deselection Flagging up quality issues Ownership British Library Legal Deposit Libraries
