Schiltberger's "Reisebuch" contains not only a record of his own experiences and a sketch of various chapters of contemporary Eastern history, but also an account of countries and their manners and customs, especially of those countries which he had himself visited. First come the lands "this side" of the Danube, where he had travelled; next follow those between the Danube and the sea, which had now fallen under the Turk; after this, the Ottoman dominions in Asia; last come the more distant regions of Schiltberger's world, from Trebizond to Russia and from Egypt to India. In this regional geography the descriptions of Brusa; of various west Caucasian and Armenian regions; of the regions around the Caspian, and the habits of their peoples (especially the Red Tatars); of Siberia; of the Crimea with its great Genoese colony at Kaffa (where he once spent five months); and of Egypt and Arabia, are particularly worth notice. His allusions to the Catholic missions still persisting in Armenia and in other regions beyond the Black Sea, and to (non-Roman ?) Christian communities even in the Great Tatary of the steppes are also remarkable.
