This year, we had a healthy quantity of beautiful, inventive, arresting, unforgettable book cover designs, many of which deserve recognition. Now, of course, since it’s the end of the year, we are socially obligated to ask, but which were the very best? So I wondered: which were the very best? I know what looks good to my laywoman’s eye, but which were really marvelous and which simply pretty? To make sense of it all, I asked seventeen designers whose own work I have deeply admired to talk about their personal favorite book covers of 2016.
