How To Shop In Used-Book Stores
Replace books where you found them. Don’t carry on loud or long conversations. Don’t boast to the owner or manager that the old paperback of Jack Vance’s “The Dying Earth” priced at $5 is actually its scarce Hillman first edition worth $100. Do look at the books themselves, not at a handheld device that indicates what they sell for online. Otherwise, prepare to be quietly and justly reviled by those around you.
