Socialist Worker was the publication of the International Socialist Organization (U.S.) from the group’s founding in April 1977 until its dissolution in 2019. Though SW has stopped publishing, its website dating back to 2001 is a rich source of socialist analysis and news of the working-class movement.

Socialist Worker was published and distributed nationally in newspaper form throughout its 42-year history, as a monthly, biweekly and weekly at various times. SW’s website was launched in 2001 and began publishing daily starting in May 2008, becoming a significant voice among independent media.
