Dear
As a passionate reader and lover of books i quite understand your question and its full important.No one book should be thrown.You can hire a Designer to remodel books/maybe one from an University,some student,its cost no much/Choose design you like,modern or old-fashioned/Your books will get a new look and image.
You shurely love books since ask this question.I'm just trying to open an Antiquarian shop for books and have many ideas,but my financial situation put me on hold to achieve my dream.
I hope you have success in your intention.
thank you
