Personae

UK true first, confirmed, with one refinement the census got slightly wrong: Personae is Pound's first regularly (commercially) published book, not his first book — it is preceded by the privately printed A Lume Spento (Venice, 1908) and A Quinzaine for This Yule (1908). There is no US edition of this 1909 title, so American and British collectors alike take the Elkin Mathews London printing as the first; there is no transatlantic precedence contest here.
