John Waters famously said — if you go home with someone and they don’t have books, don’t sleep with them (though he used a word that you won’t often find in this newspaper or on public radio). I respectfully disagree. Rather than accumulate books, I prefer to take a “one in/one out” approach. If a title is wonderful, I give it to a friend. If it isn’t, I put it on the giveaway shelf at work. I have a small number of treasured books at my house, including an autographed copy of “Role Models,” by Waters, but I have no interest in building a personal library of works that I will rarely if ever revisit. — Ari Shapiro
