You checked out an alien book from the 000 section of your library yesterday. You forgot it on the table, so you went back before school to find it. Oh no! The aliens escaped from the book and stole some of the Dewey Decimal numbers from the spine labels of other books! Now five different sections are missing their numbers!. Without the numbers, no one knows how to find anything or where to put the books back! The library will be a disaster! You know the librarian will here in 45 minutes, and you want this whole mess fixed before they return. Can you solve all five puzzles to get the numbers back on the books before the librarian returns?
