Built upon a collaborative model, PHAROS demonstrates the transformative potential of international cooperation in the stewardship of cultural heritage. By combining financial resources, technical expertise, staff practices, and archival collections, PHAROS has generated technological innovations and research opportunities at a scale that goes far beyond the reach of any individual institution. Likewise, the consortium benefits from the diversity of perspectives contributed by its members with their different cataloguing traditions, research priorities, institutional histories, and national approaches to cultural heritage.
