OAIsterin kautta voi hakea aineistoja sadoista korkeakoulujen ja tutkimuslaitosten digitaalisista arkistoista.
OAIster (Open Archives Initiative) "harvests" collections of digital resources from academic and research-related institutions. It focuses on materials (reports, studies, other documents) created at respected academic and research institutions. Much of this material is not retrieved by more "general" search engines.
