Children of the library love to push the books that have been carefully edged back into the shelf. This causes books to fall over, fall on the floor, and become a general state of disarray.
I say, stop the madness! If the children WANT the books at the back of the shelf, so be it.
And it worked.
Now if I could only get them to stop using the shelves as ladders. Then the library world would be a better place.
