'In this fascinating and exhaustively researched study of the 'republic of letters' in the seventeenth century, Fabian Montcher examines the life of Vicente Nogueira (1586–1654), a highly educated but mostly unpublished Luso-Hispanic bureaucrat, intellectual, book editor, and eventually book buyer and library advisor … Montcher's careful reconstruction of Nogueira's life and importance is built on an impressive body of archival as well as printed primary sources and an extensive examination of secondary sources pertaining to Nogueira's many correspondents.'
