John Wiley & Sons is buying Blackwell Publishing in a marriage of two medical publishing giants. Hoboken-based Wiley will shell out £572 million (around $1.08 billion) for Blackwell, headquartered in Oxford, UK. Blackwell’s 2005 revenue was $380 million, about what Wiley’s scientific, technical and medical division generated. The combined business will publish approximately 1,250 scholarly peer-reviewed journals along with an extensive selection of books, Wiley said. Blackwell titles include The American Journal of Gastroenterology, Epilepsia, The American Journal of Transplantation and the Journal of the American Geriatrics Society. Wiley publishes Arthritis & Rheumatism, The Hospitalist, Hepatology and Annals of Neurology, among other titles.
