Visible Misdirection Two-step

Looking for a book on Go, get a reference to 794.2 C435g. Since I’m on the first floor and I recall that the 800s are there, I walk over, and the sign on the end of the bookshelf loudly says

600 – 899

So I’m there, right? Wrong. I turn the corner and see a book 808 in what ought to be a wrong place. I then step back to the start of the shelf and see low 600s. So I scan to where 700 should be and I finally see a divider (a binder) with the label

700 – 799 on 5th floor

Well, (don’t) thank the shelf-end label. It obviously should have read

600 – 699
800 – 899
——————————–
700 – 799 on 5th floor

because the shelf did not contain “600-899”, as anyone reading that label would infer. The shelf-end label was a misdirection. It is trivially easily correctable.
