The Travels of Marco Polo, v. 2 -- modern translation of one of the great travelogues.
Kepler (1920) -- a fairly brief biography of one of the key Renaissance scientists.
Library of the World's Best Literature, Ancient and Modern, v.1 -- this is pretty much exactly what it says: an enormous grab-bag of literature, in alphabetical order by author. (This volume goes through "Am".) Most is 19th century, but there's a lot of older material mixed in, some of it relatively unusual -- writings of Kings Alfred the Great and Alfonso the Wise; poems of Baltazar de Alcazar; writings of Aelianus Claudius (and a lot of other Romans); and so on. Useful reference work, worth at least a skim.
