In an engaging, revisionist study, John M. Carroll argues that in the century after the Opium War, Hong Kong's colonial nature helped create a local Chinese business elite.

By the end of the nineteenth century, the colonial government saw Chinese businessmen as allies in establishing Hong Kong as a commercial center. The idea of a commercially vibrant China united them. Chinese and British leaders cooperated on issues of mutual concern, such as the expansion of capitalism and political and economic directions for an ailing China.

These Chinese also found opportunities in the colonial system to develop business and commerce. In doing so, they used Hong Kong's strategic position to underscore their own identity as a distinctive group unlike their mainland counterparts. Nationalism took on a specifically Hong Kong character. At the same time, by contributing to imperial war funds, organizing ceremonies for visiting British royalty, and attending imperial trade exhibitions, the Chinese helped make Hong Kong an active member of the global British Empire.

In Edge of Empires, Carroll situates Hong Kong squarely within the framework of both Chinese and British colonial history, while exploring larger questions about the meaning and implications of colonialism in modern history.

When the Adjutant General's Office published Raphael Thian's "notes" on U.S. military geography in 1880, it produced an invaluable research tool for generations of military historians to come. In this single documented reference volume, Chief Clerk Thian traced the confusing mutations through which the divisions, departments, and districts of the Army's command had evolved since 1813.

The volume is divided into three parts, beginning with the names of the United States Army Continental Commands, the date and authority for their creation, location of the headquarters, geographical changes and discontinuances, and other details including the geographical boundaries embracing each division, department, and district. Part II is filled with background information on states and territories, and Part III lists the maps contained in The Military Atlas of the United States.

The Addenda to this edition expand and update Thian's work. Notes made by Francis B. Heitman to keep his personal copy current are included, as is the Memorandum published by the government in 1906. This addition lists all changes from 1898 through 1905.
