“Something critical happens when the cadre of bilinguals learns to read imported scrolls: they gain entry into a library. I use the word "library" to refer not to a physical building but, more broadly, to the collectivity of accumulated writings. . . . humans possess an ever-increasing store of writings, the totality of which I call the library. The transformation of an oral culture into a written one means, first and foremost, the potential entry of bilinguals into a library.”
