De la démocratie en Amérique (Democracy in America)

The dominant trap is the made-up set. Because volumes III–IV did not appear until 1840, by which time volumes I–II were several printings along, genuine four-volume sets pairing 1835 first-printing volumes I–II with 1840 volumes III–IV are scarce, and many sets sold as "first edition" marry later 1835–1839 printings of I–II to 1840 III–IV. Check every title page individually. Gosselin reprinted three times in 1835, twice in 1836, a sixth edition in 1838 and a seventh in 1839; complete second, third and fourth four-volume editions followed in 1840, 1841 and 1842.
