Is it possible to have too many books?

My addiction is books. “Fluff” I will read at the library or give away to friends, but things that truly interest or engage me, I keep. When I filled up my bookcases, I had built-ins installed in my office. Now they’re full, too. What’s the solution? Do I have to weed through my books and get rid of some? Do I stop buying books (just the thought causes me pain)? I can’t afford a bigger house…Anyone else have this dilemma?

Only slightly tongue-in-cheek
