What should I do if the cover of the book is torn white by me?

I tore the cover of the book white. The steps are as follows:

1. Use adhesive tape: Stick transparent adhesive tape on the book cover to make the book cover look neat.

2. Handwritten label: Write the title, author, publisher and other information on the white cover with a colored pen or marker, so as to identify and distinguish different books.

3. Change the cover: If you are very concerned about the integrity of the book cover, you can consider changing the new cover. You can use a transparent plastic cover or buy a thick paper cover to replace the cover.
