A Youth designed for a Bookseller, ought to have a Genius for Letters, a general Knowledge of Books and Sciences, a clear Hand, and a solid discerning Judgment. He ought to have a Taste for the Languages, and a good Memory to acquire them. His Education ought to be as liberal as if he was designed for any of the learned Sciences; and his Knowledge of Men and Things as extensive as either the Divine, Lawyer or Physician. A mere Title-Monger can never make any thing but a Bungler, is liable every Day to be imposed upon, runs out his Stock upon Trifles, and loads the Public with the Rubbish of the Press.---R. Campbell, The London Tradesman, 1747
