Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. The Wanderings of Peoples by Alfred Cort Haddon was first published in 1911 and reissued as this corrected edition in 1912. The text contains a survey of the trends in human migration, offering information on their main causes and effects.
