The Imperial Dictionary of the English Language: A Complete Encyclopedic Lexicon, Literary, Scientific, and Technological, edited by Rev.
John Ogilvie (1797–1867), was an expansion of the 1841 second edition of Noah Webster's American Dictionary.
[1] With the addition of a third supplement volume in 1855, Ogilvie increased Webster's 70,000 word coverage to over 100,000.
Although the vocabulary coverage was small by today's standards, it was the largest English dictionary at the time.
Due to disputes with the publisher of Webster's American Dictionary (G. & C. Merriam Company), the American edition of the Imperial, published by The Century Company of New York in 1883, contained a copyright notice stating: Certain owners of American copyrights having claimed that undue use of matter so protected has been made in the compilation of the Imperial Dictionary, notice is hereby given that arrangement has been made with the proprietors of such copyright matter for the sale of this work in this country.
