PurposeThis paper aims to discuss the public knowledge project (PKP) preservation network (PN), which provides free preservation services for eligible journals by collecting article content and preserving it in a network of (at the time of writing) eight “preservation nodes” using the LOCKSS system. The PKP PN was launched in June 2016. Design/methodology/approachThis paper addresses the development and implementation of a free, distributed digital PN for open journal systems (OJS) content. It discusses challenges in developing the network, in particular relating to preserving content from a set of partners who have no formal business relationship with PKP. The paper examines data regarding journals that have opted in to the network to date and considers interface usability and other barriers facing those that have not joined. FindingsWithin 18 months of launch, more than 600 journals had opted to be preserved in the PKP PN. Many more journals are eligible to join the network; the paper explores potential strategies to increase participation and identifies and proposes methods to overcome technical and communication barriers. Originality/valueThis paper describes a highly collaborative, open-source preservation initiative which forms a unique part of the e-journal preservation landscape and preserves a particularly vulnerable portion of the scholarly record.

The Council of Prairie and Pacific University Libraries (COPPUL) is piloting a cloud-based preservation service using the Archivematica digital preservation system. The service is offered to COPPUL member institutions that wish to preserve digital holdings but prefer a hosted service to installing and managing local Archivematica instances. This service is a joint effort of COPPUL, Artefactual Systems (Archivematica lead developers), and University of British Columbia (UBC) Library (the cloud storage provider). COPPUL is responsible for promoting the service, signing up new institutions and seeding the one-time set-up costs. Artefactual Systems provides account administration, installation, server administration, and user technical support. UBC Library provides fee-based server hosting and digital object storage service. This article discusses COPPUL's Archivematica-as-aservice model generally and covers certain aspects of implementation in greater detail, concluding with a discussion of future directions.
