During the German administration of the pacific islands, a South Sea Expedition was organized by the Hamburg Museum. Anthropologists were sent out to the various islands to do in-depth studies on the people and culture, which resulted in the publication of a series of invaluable books, called “Ergebnisse der Südsee-Expedition, 1908-1910”. German anthropologist Dr. Augustin Krämer and his artist wife Elisabeth did the 5 volumes on Palau, while Anneliese Eilers did 2 volumes on the remote Southwest Islands, which are culturally closer to Yap, but politically part of the Republic of Palau. These 7 culturally invaluable volumes, in old German mixed with old Palauan, and full of drawings and photographs, are found in most museum libraries in Europe, but were unknown to Palauans.
