The General Diamond Catalog
General Catalog
The Diamond general catalog gives access to the resources of its partners, described in the RDA format.
The Partners’ Catalogs
Each partner offers its readers access to the resources of its collections through its particular catalog.
The Targeted Catalogs
Diamond also provides researchers with four catalogs focused on specific areas of expertise: the written heritage of the Muslim worlds, the written heritage of the medieval Western world, the Eastern Christian world and that of the portal of the Nahḍa.

The written heritage of the Muslim worlds
Abū Yūsuf Yaʿqūb ibn Isḥāq al-Kindī, who passed away in 866, played a pivotal role as a transmittor. He effectively transmitted Greek philosophy to the emerging Islamic culture by orchestrating collaborations with Syriac monk-translators, which facilitated the development of a scientific vocabulary in the Islamic world.

Albertus: The written heritage of the Western medieval world
Saint Albert the Great, a German Dominican, was the pioneer who first introduced Greek and Arab sciences to the burgeoning European university. His writings encompassed logic, philosophy, and theology, as well as botany, astronomy, and law. He passed away in Cologne in 1280. His most renowned disciple was Saint Thomas Aquinas.

Ignatios: The written heritage of the Eastern Christian world
At the beginning of the second century, Saint Ignatius, Bishop of Antioch, was one of the earliest Christian theologians. His writings on the divinity of Christ and the episcopal organization of the Church are universally acknowledged by both Eastern and Western Churches. He met a martyr’s end in Rome.

Maryana: The portal of the Nahḍa
Maryana Marrash (1848‒1919) was a Syrian writer and poet of the Arab Renaissance (al-Nahḍa). She revitalized the tradition of literary salons in the Arab world and was among the first women to publish Arabic poetry in modern times and contribute to Arabic-language daily newspapers.
