If the spine is shelved up, the textblock hangs unsupported and will tear itself out of the binding. Don't smash the binding onto the glass. A smashed binding can break, and the pages may fall out. Keep books away from open windows and heaters Books are sensitive to humidity and heat and their life span can be shortened by exposure to environmental extremes. To transport lots of books, use a box or book truck.
Books are heavy and often slippery.
When they fall their bindings can break. Grasp the book by the middle of the spine, not the head cap, to remove it from the shelf. The headcap will tear and the spine may come off.
