I love a book that has been beat up.
I love a book with dog-eared pages, marking favorite spots.
I love a rumpled cover, perhaps with a coffee stain.
I love a soft spine, acquired from lying open more than it has been shut tight.
I love pages that are marked and wrinkled with water spots, which say, "I loved this part of the book so much that I couldn't stop reading long enough to come in from the rain."
I love highlights, underlining, and notes in the margin.
I love all the little mishaps that say:
This book is so loved.
