Unfortunately, or fortunately, the speech I have paraphrased is based on a misconception. The notion of a scattered library reborn in all its richness wherever a reader might find himself has a certain Pentecostal loveliness, each reader receiving, like the fire that rained on the apostles from Heaven, the gift of numberless tongues. But just as a certain text is never expressed identically in different tongues, books and electronic memories, like electronic memories and the memories we hold in our mind, are different creatures and possess different natures, even when the text they carry is the same. As I argued in “Saint Augustine’s Computer,” they are instruments of particular kinds, and their qualities serve diverse purposes in our attempt to know the world. Therefore any opposition that forces us to eliminate one of them is worse than false: it is useless. To be able to find, in seconds, a half-remembered quotation from Statius or to be able to read at a moment’s notice a recondite letter from Plato is something almost anyone can do today, without the erudition of Saint Jerome, thanks to the electronic technology. But to be able to retire with a dog-eared book, revisiting familiar haunts and scribbling on the margins over previous annotations, comforted by paper and ink, is something almost anyone should still be able to do, thanks to the persistence of the codex. Each technology has its own merits, and therefore it may be more useful to leave aside this crusading view of the electronic word vanquishing the printed one and explore instead each technology according to its particular merits.
Perhaps it is in the nature of traditional libraries that, unlike the human brain, the container is less ambitious than the contents. We are told that the cerebral neurons are capable of much more knowledge than however much information we store in them, and that, in the maze of our lobes, many of the immeasurable shelves running along our secret corridors remain empty for the whole of our lives — causing librarians to lose their proverbial composure and seethe with righteous envy. From birth to death we accumulate words and images, emotions and sensations, intuitions and ideas, compiling our memory of the world, and however much we believe that we cram our minds with experience, there will always be space for more, as in one of those ancient parchments known as palimpsests, on which new texts were written over the old ones, again and again. “What is the human brain,” asked Charles Baudelaire in 1869, “but an immense and natural palimpsest?” Like Baudelaire’s almost infinite palimpsest, the library of the mind has no discernable limits. In the libraries of stone and glass, however, in those storerooms of the memory of society, space is always lacking, and in spite of bureaucratic restraint, reasoned selection, lack of funds, and willful or accidental destruction, there is never enough room for the books we wish to keep. To remedy this constraint, thanks to our technical skills, we have set up virtual libraries for which space approaches infinity. But even these electronic arks cannot rescue for posterity more than certain forms of the text itself. In those ghostly libraries, the concrete incarnation of the text is left behind, and the flesh of the word has no existence.
Virtual libraries have their advantages, but that does not mean that solid libraries are no longer needed, however hard the electronic industry may try to convince us of the contrary, however hard Google and its brethren may present themselves as philanthropical entities and not as exploiters of our intellectual patrimony. The World Digital Library, an international library supported both by Unesco and by the U. S. Library of Congress, the Bibliothèque nationale de France, and other national libraries, is a colossal and important undertaking, and even though part of the funding comes from Google, it is (for the time being) free from commercial concerns. However, even when such remarkable virtual libraries are being built, traditional libraries are still of the essence. An electronic text is one thing, the identical text in a printed book is another, and they are not interchangeable, any more than a recorded line can replace a line embedded in an individual memory. Context, material support, the physical history and experience of a text are part of the text, as much as its vocabulary and its music. In the most literal sense, matter is not immaterial.
