I've got The Best of Broadside 1962-1988: Anthems of the American Underground from the Pages of Broadside Magazine (I can't get access to this page at present; see THIS PAGE, instead), and have Broadside [Songs of Our Times from the Pages of Broadside magazine], vols. 1-3 (Oak/Broadside, 1964-1970). I'd like to know much more about the magazine's influence on the Folk Revival scene.
