The International Brotherhood of Bookbinders (IBB) was a labor union representing bookbinding workers in the United States and Canada.
The union was founded on May 5, 1892, as a split from the International Typographical Union. In 1898, it received a charter from the American Federation of Labor, and in 1919 it absorbed the small International Brotherhood of Tip Printers. By 1926, the union had 14,000 members.[1]
The union was affiliated to the AFL–CIO from 1955, and by 1957, its membership had grown to 58,344.[2] On September 4, 1972, it merged with the Lithographers' and Photoengravers' International Union, to form the Graphic Arts International Union.[3]
