Sorting a bookshelf: the solution

See the original puzzle

I am disappointed in all you readers, because no one corrected me! I thought it would require five moves to complete this puzzle, but in fact you can do it in four. I know I was amazed.

To represent the solution, 1s will represent fiction, and 0s will represent nonfiction. Now, hopefully the spacing will work out…
