In "The Swan Thieves" by Elizabeth Kostova, the sensory experience of reading is emphasized, particularly the unique and nostalgic smell of books. This quote underscores the emotional attachment people have to books, whether they are new or have aged over time. The scent of a book can evoke memories and feelings, making it an irreplaceable part of the reading experience.

The mention of this specific sensory detail speaks to the broader theme of the joy of literature and the deep connection readers form with books. Giving up the smell of books would mean losing a significant aspect of the reading journey, highlighting the importance of physical books in our lives.
