I don't like this term. All the best libraries contain books waiting to be read. The term "antilibrary" suggests something that stands in opposition to the library, like a Board of Censorship or book-burning fascists. Taleb makes an excellent point in the quoted passage, but he's hit on the wrong term. But why do the books look at you menacingly? My unread books (and they are many) look at me invitingly.
