This report describes a set of additional external research services — the discovery portals, primary-source databases, and text/edition platforms that scholars actively use to do research — beyond the core RESILIENCE platforms. The emphasis is on services scholars use directly in their day-to-day work (discovery, reading, transcription, edition). Data-management and repository services are treated as supporting infrastructure rather than as the main subject. The intention is to orient researchers, data stewards, and partner institutions to services they are likely to encounter in the wider Open Science ecosystem.
