* The new owner of the bookshelf: The most likely scenario is that the new owner of the bookshelf will also acquire the books. After all, why buy a bookshelf without anything to fill it?
* A new home for the books: The seller might move the books to another bookshelf in their home or donate them to a library, charity, or bookstore.
* Packing and storage: The books might be packed away temporarily while the seller decides what to do with them.
* Getting rid of the books: The seller might choose to give the books away for free, sell them individually, or even throw them away if they're old or damaged.
It's all about the seller's preferences and the condition of the books!
