Books should be lined up vertically on a shelf, rather than stacked or set horizontally. Improper storage such as stacking can cause the binding to break down, resulting in the dissolution of the book’s structure. Books should be placed alongside similarly-sized books to prevent bowing. Placing large books alongside smaller books could, over time, encourage the top of the cover to sag outward, resulting in a curved, irregular appearance. If you have a wide array of sizes and shapes, group them according to size as much as possible, using thin metal bookends to corral each size. Spacing books loosely will allow them to lean, resulting in weak binding and warped covers. Books should fit snugly against each other, but should not be packed in tightly, as this, too, could damage the binding. Ideally, books should be spaced in such a way that they all stand upright, with enough wiggle room to allow a small finger to wedge between them.
