<human>:  What is the best way to store antique books?
<bot>: The best way to store antique books is to keep them in a cool, dry area that is free from direct sunlight and dust. They should be stored on their sides or spine down to reduce further wear on the covers and pages. Use acid-free materials, such as boards and paper, when storing the books to help prevent them from becoming brittle and yellowing over time. For added protection, books may be covered in a sleeve or wrapping paper and kept in archival quality boxes or special bookcases that are designed for storage.
