What two things are done when a book is ordered before being placed on a shelf in the library?

1. The book is processed, which includes adding a library barcode, spine label, and other necessary markings for identification and tracking purposes.

2. The book is cataloged, which involves assigning it a call number based on its subject matter and author, so that it can be easily located on the library shelves.
