The PEPRS project aims to create a registry of e-journal archiving activities to help libraries assess digital preservation of e-journals. Phase 1 involved piloting a database of e-journals archived by 4 digital preservation agencies and national libraries. This identified issues around inconsistent ISSNs, holdings information, and terminology. Phase 2 will further develop the registry service and involve international users in testing to help establish governance. The registry will provide a searchable list of e-journals and details on what organizations are preserving which volumes and under what terms of access.
