My (academic) library does. We send out a student worker with a laptop on a book cart to scan all the books on a shelf, then the next shelf, etc. The system flags if anything is missing or out of order, so the student can fix the order right then.

When I worked in a public library, every librarian adopted a section of shelves and, when it was quiet, went and made sure it was in proper order.

Warehouse ops manager here, we call our process scheduled counts & invoice counts.

We have about 25,000 locations for parts. We count a few sections each day for our scheduled counts, and we count the entire place 3 times a year by doing it.

That helps us find and address things that may be misplaced lost or just wrong but that haven't been an issue for about 4 months.

Alternately we have a process that we used to count every location we picked parts from the day before.

The combination, when done correctly and not just fucking the dog, definately keeps you good.

I'm sad we no longer do the daily counts as it makes bigger problems than being able to check on incorrect orders within a day or 2 and not months later when no body can remember anything.

I might actually like working in a library now that I think about it

I worked part time at my college library for a bit and one of my jobs was called "shelf reading", where I'd just walk up and down the rows making sure the book numbers were in the right order. It was pretty tedious.
