Bookstore needs a lot of bookshelves to display books. The owner of the bookstore must know which shelves are good for books. Bookshelves look similar to other shelves for selling groceries but they are totally different. Why different? Bad designed bookshelves will buckle the books.
The above bookshelf buckles books. In inclined position, thicker books can withstand their own weight whereas thinner ones cannot. This is an example of bad design bookshelves whose vertical boards or plans had been designed in upright positions. But good design ones are designed following the inclined position of books.
Look at the following bookshelf design. The books lie wholly on the surface of the shelves. They will not buckle. So, if you are a bookstore owner, make sure that the bookshelves that you buy are of good design.
If you have a private library at home, to prevent the buckling of books, you can buy an inclined bookshelf or bookends to prevent your books from buckling. by Charles Roring in Manokwari of West Papua - Indonesia
