well-worn favorite book; beloved book showing signs of use
Literary term for a book that has been handled and loved so much it shows wear; implies deep personal attachment.
My grandfather's well-worn favorite book had many notes written in it.
He treasures his beloved book, which he has read over and over again.
From 手沢 (しゅたく, 'hand moisture' or 'handling wear') + 本 (ほん, 'book'). The exact historical derivation is uncertain, but the term evokes a book worn by the touch of its owner.
