  • Multiple threats to digital material. Relate to the loss of control that comes from no longer ‘owning’ content. Can we still access material after cancellation? What happens if a title is cancelled and taken offline?
  • Each LOCKSS box (at a IP address) independently collects content directly from the publisher; publishers can control which LOCKSS boxes do and don’t ingest content. Web ingest is never perfect; and the imperfections in collection are random. The LOCKSS boxes compare the collected content and come to consensus on what is the authoritative version and correct all the random errors so each LOCKSS box has the authoritative version.
  • Approaches are relatively new, and haven’t had to weather significant challenges. What is needed to support their activity? What are the library roles? What are the roles of JISC? Of RLUK?   Libraries trying to manage risk best - mitigate risk through participation in preservation initiatives. Different institutions have different priorities – LOCKSS help build collections, Portico provides a assured service. However, amongst the most common trends for motivation are that these services: - provide post-cancellation access (which has the added incentive of saving money). - insure against loss (and discard print, which saves money(?)). Take-up is relatively small, when compared with the total number of UK HE institutions Further incentives, or motivations – or education! - does the UK community need? More advocacy? Or is it just a matter of time?
  • These are the threats the literature show actually cause the vast majority of data loss.
  • JISC funding to support our efforts on community development. Two funding streams – first from institutional contributions to support technology, and to cover technical support. Our funding supports broader development – of the approach, of the community.   This work has implications for ‘shared services’ – shared information Even though LOCKSS has a model of replication, it doesn’t mean duplication.
  • The UK LOCKSS Alliance empowers libraries to continue their role as stewards of content in the digital environment. In summary: Build an archiving model that will last. Involve libraries in the design and oversight of these organizations.  
  • Thanks for listening.
