The #ArchgivesHashtagParty of the @usnatarchives of this month has the motto #ArchivesUnderTheSea wich fits half our archives but specially this work from our library: "In Meerestiefen. Geschichte der Erforschung und Eroberung der Meere" (In the Depths of the Seas. History of the Exploration and Conquest of the Seas), published in Germany in 1891 by Carl Falkenhorst (1853-1913).
