Library Edition, three volumes. Geist's Grave, New Rome, and The Lord's Messengers first appeared in the 1881 Poems, of which Archive.org has no scan dated 1881; 1885 is the earliest witness on disk. Westminster Abbey and Poor Matthias first appear in book form here. Men of Genius is The Lord's Messengers in this printing; membership is by hand, as the membership note says.
Numbers rank the poems whose position in the book is known; they are not page numbers.
