1. Box everything that you can. Anything left unboxed in a storage unit may get dusty.
2. Label boxes clearly so you can identify the contents and keep an inventory.
3. Store heavy items, such as books, in small boxes, to make them easier to carry. Store books flat to avoid damaging their spines. Use empty bookshelves to stack boxes of books.
4. Avoid packing items in sealed plastic bags, as humidity may cause mildew.
