Five years after its founding in 1898, the SK decided to publish a newsletter. The magazine was called Journal des Correspondances and appeared monthly from June 1903 onward.
The magazine was initially in French, but the need to reach Flemish workers was immediately felt. However, the SK did not yet have many followers in Flanders, so publication of a Dutch edition was not immediately initiated. This gap was filled by including one Dutch-language page in each issue. Only from 1907 onwards was the Korrespondentieblad published as a Dutch-language counterpart to the Journal des Correspondances .
The magazine was used for reporting on the internal workings of the SK and for disseminating the SK's views on domestic and international events. Leading figures within the socialist movement, such as Huysmans, Vandervelde, and De Brouckère, wrote opinion pieces, and it also advertised congresses and other important events.
The magazine came to an abrupt end with the outbreak of the First World War in 1914. From 1918 onwards, publication was resumed, but now under the title De Belgische Vakbeweging (The Belgian Trade Union Movement ).
The Correspondence Sheet covers the period 1907–1914 and is complete. The source has been made fully searchable using OCR.
