 		<meta property="se:production-notes">The Collected Poems of Langston Hughes (ISBN:978-1-4395-7173-6) was used for bibligraphic research. One poem, "Freedom Seeker," seems to have been cut off in the original printing. The anthology I was referencing has a restored ending but I am not sure where the restored ending comes from, so I am assuming that the full poem is not in the public domain and omitted it from this collection.</meta>
