But the invasion of robot-books is unsettling for another reason. I think we can all agree that it’s O.K. for robots to take over unpleasant jobs — like cleaning up nuclear waste. But how could we have allowed them to commandeer one of the most gratifying occupations, that of author?

Which brings me back to Lambert M. Surhone. Might he be a robot? Reading the fine print, I traced some of Surhone’s books to a VDM branch office in the island nation of Mauritius, off the coast of Madagascar. I called. As the faraway phone rang, I fantasized about what I would say to Surhone. By now I imagined him as a character in a Vonnegut novel, and so I was tempted to ask whether he hailed from Tralfamadore, the planet inhabited by robots. But I never had a chance. No one at the company answered the phone.

Then, when I least expected it, Surhone came for me. One day, a book titled “Pagan Kennedy” popped up on Barnesandnoble­.com, priced at $50. The lead editor: Lambert M. Surhone. I was both thrilled and creeped out. Reader, I ordered it. Within a few days, the book appeared on my doorstep. The cover was adorned with a stripy abstraction that looked like a beach towel. Inside was the Pagan Kennedy Wikipedia entry, and then a random collection of wiki-text tenuously connected to my path through life. (About a quarter of the book is devoted to Dartmouth College, where I worked as a visiting writer a few years ago.) Some of the text is so small you might need a jeweler’s loupe to read it. So the book was, as advertised, Wikipedia content — though it’s hard to imagine anyone would want it in this format.

Around that time, I also heard from a managing director of VDM, who responded to my badgering questions about robots. “Our wiki-books are produced by a group of about 40 editors,” Wolfgang Philipp Müller told me via e-mail. “Editors start at A and end their work at Z. Every topic that has enough content for a book is our target.” He said that last year, the company sold about 3,000 wiki-books — not a lot. Still, with prices that average around $50, it’s likely the company sees a high profit on each one.

Müller assured me that the editors are human. But many of the titles of these books suggest the mind of a machine at work. It’s hard to imagine a person signing off on, for instance, a book titled “Storage Ring: Particle Accelerator, Particle Beam, Accelerator Physics, Beamline, Australian Synchrotron, Cyclotron, Dipole Magnet, Electromagnetism.” Also, there were other robotlike errors: one of VDM’s books about the rock band the Police was paired with a cover illustration of actual police officers.
