This book is based on a smaller volume issued by the Johns Hopkins Press in 1900 under the title "The Diplomatic Relations of the United States and Spanish America," which contained the first series of Albert Shaw Lectures on Diplomatic History. That volume has been out of print for several years, but calls for it are still coming in, with increasing frequency of late.
