PHAIDRA (Permanent Hosting, Archiving and Indexing of Digital Resources and Assets) is the University of Vienna repository for long-term archiving of digital objects and collections. PHAIDRA hosts various types of digital objects (documents, pictures, audio, video, research data) from all disciplines of the University. PHAIDRA offers a search facility to identify specific objects, and each object can be viewed, downloaded, used and reused to the extent permitted by law and by its associated licences. The objects and collections on the PHAIDRA platform are sourced from all departments, libraries, collections and archives at the University of Vienna. All members of the University of Vienna are authorized to upload digital scientific objects to PHAIDRA after logging in.
