The Amalgamated Union of Building Trade Workers (AUBTW) was established on 1 January 1921 by the amalgamation of the Operative Society of Masons, Quarrymen and Allied Trades of England and Wales, the Manchester Unity of Operative Bricklayers' Society and the London Order of Operative Bricklayers' Society.

The 'Trade Circular and General Reporter' was the internal bulletin sent to members of the AUBTW and included Executive Council minutes, notices, lists of recipients of compensation, correspondence and articles on items of general interest. As the circulars include full minutes they tend to be considerably larger than a magazine or newspaper (the volume containing the first 8 circulars consists of 950 pages).

The earliest volume of the 'Trade Circular and General Reporter', covering the first year of the new trade union, is available through the Modern Records Centre's catalogue:
