I'm torn between Carlo Ginsburg's book of late medieval cosmology, The Cheese and the Worms, and the recent acquisition of the French translation of a Spanish textbook on descriptive linguistics. I bought the second one mostly because I realized I could read 80% of it -- the technical vocabulary is all Latinate, and generally cognate with the equivalent English terms -- and it would be good reading practice.
*Also, an honorable mention to Henry Petroski's books on the history of the bookshelf and the pencil (which were deeply fascinating! Cultural history as well as engineering.)
