As recently as 2001, there were few lengthy discussions in English on the Imjin Waeran (Hideyoshi's invasion of Korea) aside from William George Aston's contribution to the Transactions of the Asiatic Society of Japan (‘Hideyoshi's invasion of Korea’) from the 1870s and 1880s and a clutch of articles. The last nine years, though, have seen an extraordinary production of published works and the appearance of translations of primary sources, some full, some partial, some finished, and some on the way. Stephen Turnbull's Samurai Invasion appeared in 2002. Just three years later, in 2005, Samuel Hawley published The Imjin War, and now we have Kenneth M. Swope's A Dragon's Head and a Serpent's Tail. The three books are each written from the perspective of the three main belligerents: Turnbull working from Japanese sources, Hawley from a Korean perspective, and Swope from Ming sources. These three offer detailed narratives on the war and allow English-language scholarship to set aside general narrative in favour of specific research agendas.
