Books on the loose!

I can tell from the shelves there are books on the loose,
Like that song with the lines about a moose in the hoose.
Scattered they lie on tables like the wounded in battle,
Round them up I must like great herds of cattle.
Out to them I trudge like a shepherd in fog,
Or another part in the library machine, a cog
And build mini towers of books to carry home,
Back to the shelves and place in the order of tomes
As prescribed by our old friend Melville Louis Kossuth Dewey,
Knowing that it’ll be the same again real soon - oh phooey!
