There are probably a couple of reasons why someone to cover their book.
First, the bookstore will actually cover the book for you right at the point when you purchase it. That’s right, they will wrap the book right there at the cash register with a brown paper, usually branded with their name — hiding the cover of the book.
This not only protects the book but brings me to the next point, they want some privacy. A long train commute offers quite a lot of time to read, but maybe they don’t want others to know exactly what they’re reading so a book cover helps with that.
