It’s that time of year. You need holiday presents and you don’t know what to buy. Allow me to offer this gentle reminder: Books (1) are fast and easy to wrap, (2) come in multiple varieties at every price point, (3) can be ordered online or personally mailed using the U.S. Postal Service’s bargain media rate, and (4) don’t have to be new — this is a great time to support your local used bookshops, those bastions of civilization in a dark time.
