Dictionary of Americanisms (Bartlett, 1848) [Historical]
Bartlett, John Russell. Dictionary of Americanisms. New York: Bartlett and Welford, 1848.
A classic work. This is the first of several editions. Largely incorporated into more recent dictionaries, occasionally you will find an entry that has been ignored by more recent lexicographers.
