IIPC RSS Webinar: Nordic web archives for researchers: access, tools and services

This webinar will bring together speakers from three Nordic web archives to discuss access, tools, and services for researchers.


  • Anders Klindt Myrvoll, Netarkivet, Royal Danish Library
  • Jon Carlstedt Tønnessen, National Library of Norway
  • Sanna Haukkala & Samuli Sairanen, National Library of Finland

Netarkivet, Royal Danish Library

The presentation will focus on the status quo and future aspects of what, who and how of web archiving activities at the Royal Danish Library:

  • What we collect based on the Danish legal deposit act, via broad-, selective-, event- and special harvests. A finely meshed net so we get as much relevant content as possible, including focus on content behind paywall and hard-to-crawl social media.
  • Who can access the web archive? Currently the archive is only for researchers or PhD students affiliated with a Danish research institutions following an application.
  • How researchers can use the archive. For search, discovery, visualization and playback of our archives +1PB data, 3.7 million domains, +40 billion objects, 118.000 billion characters (32TB) in text/content fields, we use open source software, SolrWayback, originating from the Royal Danish Library using the UKWA Solr based warc-indexer framework. It´s possible to free-text search in the entire content of the archive and I’ll give some examples to showcase the strength of this approach.

We are currently also in the process of transitioning to PyWb from OpenWayback – in tandem with SolrWayback, for enhanced playback, especially for sites using post-request like Instagram, Facebook and many other cases. In connection with specific research projects, it is also possible to receive data from the web archive – typically as a paid service using a data agreement. We will have a look at the process as well as a few use cases, from smaller extractions to massive amounts of data.

National Library of Norway

The Norwegian Web Archive (NWA) contains valuable sources for research on recent and ongoing transformations of culture and society. However, legal protection of copyright and privacy implies limitations on access and utilization of these data. How does the NWA work to provide access for researchers and develop relevant tools and services?

This talk will give an overview of the NWA’s collection (2001-), how they collect data, and present their current efforts to establish access for researchers. Further, it will share experiences from implementing SolrWayback, and to develop computational tools for analysis on top of that. This involves enriching archival resources with relevant metadata, and striving to align data, access, and services with FAIR principles.

Research Librarian, National Library of Norway

Trained as a web historian, Jon has brought perspectives from the Humanities into the Norwegian Web Archive. With a passion for end-user oriented development, he has spent the last two years to facilitate researcher access, and to prototype tools and services for the research community. Jon is also affiliated with the DH-lab at the National Library of Norway.

National Library of Finland

This talk will introduce you to the basics of the Finnish Web Archive and its research use. Online materials have been harvested and deposited by The National Library of Finland since 2006 and they are available to use at legal deposit workstations on the premises of eight dedicated libraries in Finland, covering geographically large percent of the country.

The most recent amendment on The Copyright Act in 2023 has also created a possibility to make online materials available to researchers with new methods. Improving the research use and providing preserved materials to be utilized especially with methods of digital humanities (DH) will be key points in the library strategies in forthcoming years.

This talk will also cover The Finnish language model FinGPT-3 that have utilized the contents of the Finnish Web Archive and The Electronic Legal Deposit Collection.
