from Dictionary of the English Language, (1755)
While the Dictionary was going forward, Johnson lived part of the time in Holborn, part in Gough-square, Fleet-street; and he had an upper room fitted up like a counting-house for the purpose, in which he gave to the copyists their several tasks. The words, partly taken from other dictionaries, and partly supplied by himself, having been first written down with spaces left between them, he delivered in writing their etymologies, definitions, and various significations. The authorities were copied from the books themselves, in which he had marked the passages with a black-lead pencil, the traces of which could easily be effaced. I have seen several of them, in which that trouble had not been taken; so that they were just as when used by the copyists. It is remarkable, that he was so attentive in the choice of the passages in which words were authorised, that one may read page after page of his Dictionary with improvement and pleasure; and it should not pass unobserved, that he has quoted no authour whose writings had a tendency to hurt sound religion and morality.
The necessary expense of preparing a work of such magnitude for the press, must have been a considerable deduction from the price stipulated to be paid for the copy-right. I understand that nothing was allowed by the booksellers on that account; and I remember his telling me, that a large portion of it having by mistake been written upon both sides of the paper, so as to be inconvenient for the compositor, it cost him twenty pounds to have it transcribed upon one side only.
He is now to be considered as 'tugging at his oar,' as engaged in a steady continued course of occupation, sufficient to employ all his time for some years; and which was the best preventive of that constitutional melancholy which was ever lurking about him, ready to trouble his quiet. But his enlarged and lively mind could not be satisfied without more diversity of employment, and the pleasure of animated relaxation. He therefore not only exerted his talents in occasional composition very different from Lexicography, but formed a club in Ivy-lane, Paternoster-row, with a view to enjoy literary discussion, and amuse his evening hours. The members associated with him in this little society were his beloved friend Dr. Richard Bathurst, Mr. Hawkesworth, afterwards well known by his writings, Mr. John Hawkins, an attorney, and a few others of different professions.
from James Boswell, Life of Samuel Johnson (1791)
Down to the time of the first lexicographer (Heaven forgive him!) no author ever had used a word that was in the dictionary.
