Scholarly Serials & Other Published Online Heritage: Measuring What Is Kept
Gaëlle Béquet Peter Burnhill
Five years on from iPres2019, our focus then on rescue, six additional Keepers now report in to extend the reach of the Keepers Registry: the Internet Archive, Merritt Preservation Repository (California) and the national libraries of France and Spain, plus Cariniana Network (Brazil) and ZBW (Leibniz, Germany). They join others, such as Portico, CLOCKSS, Global LOCKSS Network, PKP-PLN, KB (Netherlands), Library of Congress, Scholars Portal and HathiTrust.

Disclosure by archiving organisations on the details of content they preserve, and how, enables the Keepers Registry to act as the global monitor of what online continuous resources are safe on digital shelves. That also allows analysis of the aggregated metadata held in the ISSN Portal to shine a light what is unknown and at risk of loss. 

We report details of progress for scholarly journals from the 'Big Publishers', the approach being taken for OA content and share statistical evidence on the high rates of unknown archival status for scholarly works from specific countries, some surprising. 

There are strategic choices to be made. What do you advise? Prioritise the product of scholarship or change tack and try to ensure that what is issued online around the world is kept as published heritage. The latter requires request to national libraries that they declare what content is actually being kept safe.
