The International Internet Preservation Consortium is seeking proposals for presentations and workshops at the next conference and general assembly to be held at Stanford University in California, USA on the 27 and 28 April 2015. The theme is "Innovation, connection and co-operation in web data"; see more below. ** *Proposals* The presentations should be aimed at 20 mins. for single papers and up to 60 mins. for panel sessions of up to 3 speakers. Workshops or training for specific web archiving tools, concepts, or issues can be up to half a day in length. Abstracts should include the name of the speaker, a title, conference sub-theme (see below) and be no more than 300 words. Proposals should be emailed tojason.webber@bl.uk <mailto:jason.webber@bl.uk>by*Friday 28 November 2014*. All abstracts should be in English. All submissions will be reviewed by the Conference Committee and those which are accepted will be notified by Friday 19 December 2014. http://netpreserve.org/ga2015-call-papers *Theme* Innovation, connection and co-operation in web data The history of web archiving has been one of the interaction between fast-evolving web technologies and the processes and technologies used to archive the web: a perpetual arms race between developers of the live web, and the archivists charged to preserve the record. This interplay is the theme for this year's GA at Stanford, in the heart of Silicon Valley. It has four sub-themes: ** *Access* How can the providers of archives harness the power of new technologies to improve the experience of users, and to enable them to do more with the content that archives provide? Which are the innovative projects that show the way, and which are the emerging technologies that will be next? Can web archiving developers co-operate more and better with others in the field, to mutual benefit? There are common technical issues at play, such as the scalability of technologies such as Apache Solr for big data: how might expertise best be shared? ** *Research* What does truly innovative research look like? How are researchers, both inside and outside the academic sector, using the archived web now, and what are the questions they would like to ask of the archive, but cannot (yet)? Is there yet innovation in the *methods* that researchers are using; or is the use of web archives still analogous to older paradigms of the use of printed objects? ** *Harvesting* How can archivists and indeed all those who rely on crawler technologies keep pace with the ever-changing technologies by which content is delivered? How might developers and archivists work better together so that questions of "archivability" become part of the design process? ** *Preservation* As the web evolves, so do the formats in which it is delivered, and formats that were once innovative soon become obsolescent. How might developers and archivists work together to ensure that data can be preserved, and effective global standards adopted?
