Great article, thank you.

Librarians aren't as dumb as you make them out to be. Several times I've asked a librarian to locate a mis-shelved book I really needed, and they've always succeeded. I gather it's a pain, but it's considered a big victory.

Also, as a library patron, they've taught me to take any book that I notice mis-shelved and set it on a nearby table.

It never ceases to amaze me how human intelligence and care can transform algorithms that are theoretically brittle into systems than endure for centuries.
