The lawyer Johannes Tiberius Bodel Nijenhuis (1797–1872), director of the publishing house Luchtmans, for 25 years a member of the Maatschappij der Nederlandse Letterkunde, was a passionate collector of cartographical and topographical material. The collection contains 60,000 maps (of which 3,000 drawings), 1,500 atlases, 24,000 topographical prints, 1,600 drawings and the archive of Youssouf Kamal's Monumenta Cartographica Africae et Aegypti. Oriental Collections From its very onset the study of the Orient was of vital importance to the new university. Theologians studied the Semitic languages to perceive the meaning of the Bible. Political and commercial interests prompted the new-born Dutch Republic to establish relations with its enemies' enemies, among whom the Ottoman Empire, then at the zenith of its power. In the course of its expansionist policy the Dutch Republic secured possession of the Indonesian archipelago and other territories in South East Asia. In Japan, Dutch merchants maintained a trading post to the exclusion of all other European powers.

Oriental Studies are still flourishing at Leiden University, and the Oriental Collections are still growing to serve the needs of the national and international scholarly community. The Oriental Collections of Leiden University Libraries are known as the Legatum Warnerianum (Warner's Legacy), referring to Levinus Warner (1619–1665), envoy to the Sublime Porte at Constantinople, whose collection of 1,000 Middle Eastern manuscripts forms the core of the present-day Oriental Collections. In 1659 following the death of the Ottoman bibliophile-encyclopedist Kâtip Çelebi his library was sold. At the time it was the largest private library in Istanbul, and Warner acquired part of it for the University of Leiden. The Oriental Collections nowadays contain 30,000 manuscripts and 200,000 printed books on subjects ranging from Archaeology to Zoroastrianism and in languages from Arabic to Zulu. Bibliotheca Thysiana The Bibliotheca Thysiana was erected in 1655 to house the book collection of the lawyer Joannes Thysius (1622–1653). Upon his early death, he left a legacy of 20,000 guilders for the building of a public library ("tot publycque dienst der studie") with a custodian's dwelling. Designed by the architect Arent van 's-Gravensande, the building follows the Dutch Classical style and is regarded as one of the jewels of Dutch 17th century architecture. It is distinguished by its balanced proportions and the purity
