No library is richer in its field of concentration (the former Dutch East and West Indies) than that of the Royal Institute of Linguistics and Anthropology (the K.I.T.L.V.). Any listing of its contents accumulated over the past 175 years, serves as a useful general bibliography for historians as well as anthropologists and linguists. Between 1971 and 1975, the Institute's documentalist, G.A. Nagelkerke, prepared five of those, all of them published by the Institute at Stationsplein 10, Leiden, and still available through it.
