The main collection of the Ballads was published in the 1890s, in two volumes: "Barrack-Room Ballads and Other Verses" (1892, the first major publishing success for Methuen) and "The Seven Seas" (1896), sometimes published as "The Seven Seas and Further Barrack-Room Ballads". In both books, they were collected into a specific section set aside from the other poems, and can be easily identified. ("Barrack-Room Ballads and Other Verses" has an introductory poem ("To T.A.") in Kipling's own voice, which is strictly not part of the set but is often collected with them.)
