¹ Since the 1970s Walravens has published more than 150 books, most of them bibliographies. See, for example, his works relating to famous and less famous orientalists or ‘old China hands’ such as Karl Gützlaff (1803–1851), Vincenz Hundhausen (1878–1955), Ferdinand lessing (1882–1961), Paul Pelliot (1878–1945), Albert Grünwedel (1856–1935), W. A. Unkrig (1883–1956), Joseph F. Rock (1884–1962) etc.

² This is well documented by the publication of several books and articles, by a forthcoming, new comprehensive biography of Wilhelm (by Ursula Ballin, as mentioned in Walravens, p.12) and by two workshops with international participants held in Bad Boll in 2002 and at the University of Frankfurt in 2004.
