"Negro World: Poetry for the People": a Collection of Poems (1919-1921)
One exception might be Lucian B. Watkins, who also published throughout the 1910s in The Crisis. Watkins published a number of poems in "Poetry for the People" between 1919 and 1921, and his death in 1921 was followed by several tribute poems from readers and fans.
A few additional poems from Negro World can be found digitized by Jessica Covil, a Ph.D. student at Duke University, here.
