Until 1935, the TACB was a loose umbrella organization of two independent federations: the Flemish federation (primarily Ghent) and the Verviers federation. After the formation of a separate national federation in 1908, the process of centralization stalled. After the First World War, the Flemish federation transformed into a national federation without Verviers. Under the impetus of Alfons Segier and after the failed strike of 1934, Verviers finally joined the national federation in 1935.
The series can be divided into three. The most interesting books are numbers 11_02, 11_03, and 11_05. These books contain the minutes of the meetings of the executive board, the highest body of the umbrella organization. They cover the period 1923-1934 and thus end at the time of the merger. Number 11_01 is the minutes of the Flemish federation for the period 1910-1912. Number 11_04 contains the minutes of the various committee meetings in 1933. The committees were smaller groups that focused on a single theme. Examples include the Social Funds Committee, the Unemployment Committee, and the Administrative Committee.
The logbooks were digitized with the support of the Jules Deconinck Fund and ABVV Textiles, Clothing and Diamonds.
To facilitate online consultation, the report books were divided into sections of forty to fifty pages. Since most of the books were written in manuscript, OCR was not used.
