The Rochambeau branch library kept its card catalog years after the system went digital, in oak cabinets against the back wall, officially as furniture. The cards were frozen — nothing added after the changeover — but nobody had the heart to pulp them, and so for a while my neighborhood had two catalogs: the database, which knew what the library owned, and the cabinets, which knew things the database has never learned.
The cards knew, first of all, what people had touched. A catalog card for a popular book was soft at the corners, gray along the top edge where forty years of fingers had walked past it. The card for A Tree Grows in Brooklyn looked like it had been carried through a war. The cards for the six-volume history of the Byzantine administrative state were crisp as the day they were typed, and their crispness was information too — an honest confession, right there in the drawer, of the difference between what a neighborhood keeps and what it uses. The database records circulation. It does not record longing, and the wear on a card was longing made visible: every soft corner was a finger that had paused there, considering a different evening than the one it went on to have.
The cards knew handwriting. Typed, mostly, on machines whose quirks became familiar — the branch’s old Royal dropped its lowercase e a half-step below the line, so that every card it produced seemed to be written in a slightly falling voice. But corrections and additions were made by hand, in the small disciplined script of librarians dead before I was born. See also, the cards said, in fountain pen, and the see-alsos were editorial, human, sometimes almost sly. The card for a bombastic Victorian memoir bore a penciled see also pointing to a rival’s memoir of the same events, and if you followed the trail you discovered the two books quietly contradicting each other across a century. Some librarian built that joke by hand, for no one, for whoever. The database has cross-references too, generated in batch. Nobody has ever chuckled at one.
Most of all the cards knew order in a way that produced accidents. Card catalogs forced you to travel: to find your book you flipped through fifty neighbors, and the neighbors were the education. Looking up Moby-Dick, you passed cards for whaling logs, Melville’s letters, a monograph on rope. The digital catalog retrieves; the card catalog exposed. Retrieval gives you what you asked for, which assumes the thing you needed was the thing you knew to ask for — the fundamental, false assumption of every search box I have ever typed into. The drawers assumed the opposite. They assumed you did not quite know what you wanted, and they were right, and their rightness was the whole apparatus of serendipity that we have spent thirty years engineering away and then, in belated panic, trying to simulate with recommendation algorithms. Readers also enjoyed. The drawer never claimed to know what readers enjoyed. It just made you walk through the whole neighborhood on your way to your own front door.
I asked, once, what became of catalogs like Rochambeau’s, and the answer is what you’d guess: dumpsters, mostly, nationwide, in a quiet decade-long purge. Some cabinets were sold to restaurants for ambience. A few catalogs were saved by libraries that understood they held local history — decades of accession notes, withdrawal stamps, the paper trail of a community’s mind — and one, famously, at the American Antiquarian Society, is preserved as an artifact in its own right. But mostly the cards went the way of all superseded infrastructure, and we did not grieve at the time, because the database was genuinely better at the thing we had decided catalogs were for: finding a known book, fast.
It was only later that we noticed the catalogs had been for other things as well, things nobody had thought to list in the requirements because nobody knew they were requirements until they were gone. This is the pattern with all replaced technologies and I have stopped expecting us to break it. The new thing does the named job better; the old thing was doing six unnamed jobs on the side; the unnamed jobs simply stop being done, and the loss is discovered by symptom, years later, like a vitamin deficiency. Wandering, adjacency, the visible evidence of other people’s hands, the falling voice of the old Royal — none of it was ever in the spec. The spec was find the book. We find the books faster than any generation in history. It would take a heart of oak to say nothing was lost, and the oak, as I mentioned, went to the restaurants.
The Rochambeau cabinets disappeared during a renovation while I was away at school. The room they stood in is brighter now, and has more outlets, and I use it gratefully; this is not a complaint about a library, which serves its neighborhood better than ever and against harder odds. It is just a record, before I forget, of a machine my neighborhood once had: a wooden database, warm to the touch, that answered questions slowly, told you things you hadn’t asked, and kept — in wear and pencil and falling type — a secret second catalog of everyone who had ever stood there wanting.
