How to arrange bookshelves
Start fresh.
If you intend to primarily use your bookshelves to contain books (how novel! ), then it is best to assess your inventory before you begin. Remove all your books from your shelves, dust them off and clean and polish your empty bookshelves before you refill them.
Go through your books and decide which ones you want to keep and which ones you want to give away. You can donate books to friends, your local library or a literacy council.
