Alas, the poor phone book. Once, it was the cornerstone of American connection, an indispensable resource people relied on to find pizza shops, plumbers, and the number of the cute girl in math class. But now, when a new phone book lands on a homeowner’s doorstep, the tome most often gets tossed in the recycling bin. They might be used to press flowers, or as a booster seat or a door stop, but fewer and fewer phone books are used for what they were originally intended, to look up telephone numbers.
