Since the founding of the Industrial Workers of the World (IWW), songs have played a large part in spreading the message of the One Big Union. The songs are preserved in the Little Red Songbook.
The Little Red Songbook (1909), also known as I.W.W. Songs or Songs of the Industrial Workers of the World, subtitled (in some editions) Songs to Fan the Flames of Discontent, is a compilation of tunes, hymns, and songs used by the Industrial Workers of the World (I.W.W.) to help build morale, promote solidarity, and lift the spirits of the working-class during the Labor Movement.
The Little Red Songbook was first published by a committee of Spokane, Washington IWW members in 1909.[1] [2] It was originally called Songs of the Workers, on the Road, in the Jungles, and in the Shops—Songs to Fan the Flames of Discontent.[3] It includes songs written by Joe Hill, Harry McClintock (Spellbinder), Ralph Chaplin, T-Bone Slim, and others. The early editions contain many of the most well-known labor songs, such as "The Red Flag," "The Internationale," "The Preacher and the Slave," and "Solidarity Forever." Thirty-six editions were published between 1909 and 1995.
A Canadian I.W.W. Songbook, compiled and edited by Jerzy (George) Dymny, featuring 41 songs with a Canadian slant, was published in 1990.
An edition commemorating the centennial of the IWW's founding in 1905 was published in 2005. The latest edition of the Little Red Songbook was printed in 2010.
The 190 different songs included in the Little Red Songbook between 1909 and 1973 are collected and annotated in The Big Red Songbook, edited by Archie Green, David Roediger, and Franklin Rosemont and published in 2007.
