In response to Joseph Worcester's groundbreaking dictionary of 1860, ''A Dictionary of the English Language'', the [[G. & C. Merriam Company]] created a significantly revised edition, ''A Dictionary of the English Language''.<ref>{{cite book|last=Landau|first=Sidney|title=Dictionaries: The Art and Craft of Lexicography|edition=2nd|year=2001|publisher=Cambridge University Press|isbn=0-521-78512-X}}</ref> It was edited by [[Yale University]] professor [[Noah Porter]] and published in 1864, containing 114,000 entries. It was sometimes referred to as the ''Webster–Mahn'' edition, because it featured revisions by [[C. A. F. Mahn]], who replaced unsupportable etymologies which were based on Webster's attempt to conform to Biblical interpretations of the history of language. It was the first edition to largely overhaul Noah Webster's work, and the first to be known as the ''Unabridged''. 

Later printings included additional material: a "Supplement Of Additional Words And Definitions" containing more than 4,600 new words and definitions in 1879, ''A Pronouncing Biographical Dictionary'' containing more than 9,700 names of noteworthy persons in 1879, and a ''Pronouncing Gazetteer'' in 1884. The 1883 printing of the book contained 1,928 pages and was 8½ in (22&nbsp;cm) wide by 11½ in (29&nbsp;cm) tall by 4¼ in (11&nbsp;cm) thick. The 1888 printing (revision?) is similarly sized, with the last printed page number "1935" which has on its back further content (hence, 1936th page), and closes with "Whole number of pages 2012".  This dictionary carries the 1864 Preface by Noah Porter with postscripts of 1879 and 1884.

James A.H. Murray, the editor of the ''Oxford English Dictionary'' (1879–1928) says Webster's unabridged edition of 1864 "acquired an international fame. It was held to be superior to every other dictionary and taken as the leading authority on the meaning of words, not only in America and England, but also throughout the Far East."<ref>K. M.
