The bulletin was put out by the CNT (Confederación Nacional del Trabajo), AIT (Asociación Internacional de los Trabajadores), and FAI (Federación Anarquista Iberica). The CNT has long been affiliated with both the AIT and the FAI, sometimes referred to collectively as the CNT-FAI. Throughout its history, it has played a major part in the Spanish labor movement. During the Spanish Civil War, the CNT collaborated with other republican groups opposed to the Nationalists, and as the war went on, CNT members came to form part of the goverment of the Republic. In Barcelona, members managed the majority of the city and its functions.

This bulletin is also written in Esperanto. During the time of the Spanish Civil War, Esperanto was often used in newspapers and on the radio to keep International Brigades informed about the proceedings of the war. Esperanto was also widely spoken among Anarchists and Catalan nationalists.
