If a man can purchase but very few books, my first advice to him would be, let him purchase the very best. If he cannot spend much, let him spend well. The best will always be the cheapest. Leave mere dilutions and attenuations to those who can afford such luxuries. Do not buy milk and water, but get condensed milk, and put what water you like to it yourself. This age is full of word-spinners – professional book-makers who hammer a grain of matter so thin that it will cover a five-acre sheet of paper. These men have their uses, as gold-beaters have, but they are of no use to you. – Charles Haddon Spurgeon (1834-1892), from Lectures to My Students (1881).
