有声读物: Cambridge Medieval History, Volume 01, The Christian Roman Empire and the Foundation of the Teutonic Kingdoms

Volume 1: The Christian Roman Empire and the Foundation of the Teutonic Kingdoms "The present work is intended as a comprehensive account of medieval times, drawn up on the same lines as The Cambridge Modern History but with a few improvements of detail suggested by experience. It is intended partly for the general reader, as a clear and, as far as possible, interesting narrative; partly for the student, as a summary of ascertained facts, with indications (not discussions) of disputed points; partly as a book of reference, containing all that can reasonably be required in a comprehensive work of general history."
