For more than 40 years, I’ve been reading books professionally, as a frequent critic and later as book editor of the state’s largest newspaper. In those roles, I have had a ringside seat to observe some of the best books to be published in the last half of the 20th century—as well as a lot of the less-than-great books during that period. When you comb through thousands of books every year, you have a challenge. What, if any, of these shall I read? How will I find the time?
