Richardson started on a new track altogether.  Observing how much light was shed on the meaning of words by Johnson’s quotations, he was impressed with the notion that, in a dictionary, definitions are unnecessary, that quotations alone are sufficient; and he proceeded to carry this into effect by making a dictionary without definitions or explanations of meaning, or at least with the merest rudiments of them, but illustrating each group of words by a large series of quotations.  In the collection of these he displayed immense research.  Going far beyond the limits of Dr. Johnson, he quoted from authors back to the year 1300, and probably for the first time made Chaucer and Gower and Piers Ploughman living names to many readers.  And his special notion was quite correct in theory.  Quotations will tell the full meaning of a word, if one has enough of them; but it takes a great many to be enough, and it takes a reader a long time to read and weigh all the quotations, and to deduce from them the meanings which might be put before him in a line or two.  As a fact, while Richardson’s notion was correct in theory, mundane conditions of space and time rendered it humanly impracticable.  Nevertheless, the mass of quotations, most of them with exact references, collected by him, and printed under the word-groups which they illustrated, was a service never to be undervalued or forgotten, and his work, ’A New Dictionary of the English Language ...  Illustrated by Quotations from the best Authors’ by Charles Richardson, LL.D., 1836-7, still continues to be a valuable repertory of illustrations.

Such was the position of English lexicography in the middle of the nineteenth century, when the late Dr. Trench, then Dean of Westminster, who had already written several esteemed works on the English language and the history of words, read two papers before the Philological Society in London ’On some Deficiencies in existing English Dictionaries,’ in which, while speaking with much appreciation of the labours of Dr. Johnson and his successors, he declared that these labours yet fell far short of giving us the ideal English Dictionary.  Especially, he pointed out that for the history of words and families of words, and for the changes of form and sense which words had historically passed through, they gave hardly any help whatever.  No one could find out from all the dictionaries extant how long any particular word had been in the language, which of the many senses in which many words were used was the original, or how or when these many senses had been developed; nor, in the case of words described as obsolete, were we told when they became obsolete or by whom they were last used.  He pointed out also that the obsolete and the rarer words of the language had never been completely collected; that thousands of words current in the literature of the past three centuries had escaped the diligence of Johnson and all his supplementers; that, indeed, the collection
