Poems in "Colored American Magazine" (1900-1909)
In terms of literary contributions, the magazine is perhaps best known as the venue where Pauline Hopkins published many important short stories. Starting in 1901, Hopkins was the editor of the "Women's Section" in the magazine, and starting in May 1903, she became the literary editor of the magazine. Pauline Hopkins followed the magazine after its move, but was pushed out by financial supporters of the magazine, and resigned as editor after November 1904.
There is a very informative and well-designed site dedicated to The Colored American Magazine here. Unfortunately, it is not at present complete, and many of the high quality PDF scans of the magazine are not searchable. There is also a collection of page images of the magazine at HathiTrust.
