	https://www.oeaw.ac.at/en/ihb/research-units/digital-historiography-and-editions/research/onit Ottoman Nature in Travelogues, 1501–1850: a Digital Analysis (ONIT) This interdisciplinary Digital Humanities project analyzes Ottoman “nature” (flora, fauna, landscapes) in travelogues on the Ottoman empire, printed between 1501 and 1850.
