In 1841, 82-year-old Noah Webster published a second edition of his lexicographical masterpiece with the help of his son, William G. Webster. Its title page does not claim the status of second edition, merely noting that this new edition was the "first edition in octavo" in contrast to the quarto format of the first edition of 1828. Again in two volumes, the title page proclaimed that the "Dictionary" contained "the whole vocabulary of the quarto, with corrections, improvements and several thousand additional words: to which is prefixed an introductory dissertation on the origin, history and connection of the languages of western Asia and Europe, with an explanation of the principles on which languages are formed. B. L. Hamlen of New Haven, Connecticut, prepared the 1841 printing of the second edition.
