An American Tragedy

The 1929/1930 Horace Liveright one-volume printing carries a 'New Edition in One Volume, September, 1929' statement and is a later, reset edition — the most common look-alike, and the single-volume format alone rules out the first. Any later trade or reprint issue in one volume is a 'first thus' trap; the 1925 first is always two volumes in a slipcase.
