First edition of Noah Webster's highly important American dictionary of the English language, considered "the most ambitious publication ever undertaken, up to that time, upon American soil." (Dictionary of American Biography). Guided by a nationalistic desire to codify a distinctly American language, Webster began publishing spelling books, grammars, and readers, for children, in the 1780s. His work in lexicography began in 1800, and this unabridged dictionary was preceded by a much shorter duodecimo version in 1806, Compendious Dictionary of the English Language. With the publication of this set, "Webster set a new standard for etymological investigation, and for accuracy of definition, and included 70,000 words, as against the 58,000 of any previous dictionary." (Grolier).
