How do I ship books?

Pack books spine-down in a sturdy box, wrap them against scuffs, and fill every gap so the load cannot shift. Books get heavy fast, so split large lots across boxes and weigh each sealed box before buying postage. A Canada Post Xpresspost label from LetterAgent covers parcels up to 5 kg within Canada.

Why is box strength the first decision?

Books are among the densest things people ship. A small box of hardcovers can weigh more than a large box of clothes, and that weight punishes weak cardboard. Use a new, double-walled box or a small, sturdy single-walled one, and reject any box with crushed corners, old tape, or a soft bottom. Reinforce the bottom with two strips of packing tape in a cross pattern before you load anything. In the United States, media mail exists as a slower, cheaper book rate, while in Canada there is no direct equivalent for most senders, so book parcels usually travel at regular parcel rates in either country.

How do I protect spines and corners?

Wrap each book on its own in kraft paper or a plastic sleeve. Bare books rub against each other in transit, and that friction dulls covers and rounds corners. For hardcovers with dust jackets, slip a sheet of paper between the jacket and the cover so the jacket does not stick to it in heat. Stand books upright with spines down, like books on a shelf laid on their side, so the weight rests on the spine edge rather than on the pages. Never pack books flat in a tall stack: the bottom books carry the whole load and their pages splay. Corner protectors, cut from spare cardboard, are worth the minute they take for valuable or collectible copies.

How do I pack books so they do not shift?

Fill the box completely. Books that can slide will slide, and a shifting load is what tears covers and splits bindings. Use crumpled kraft paper or bubble wrap in every gap, including the corners, and press down gently on top before taping: if the lid springs up, add padding or remove a book. Do not use packing peanuts for books on their own, since heavy books sink through them and end up loose at the bottom. Tape all seams with packing tape, and add a second strip across the bottom for any box over a few kilograms. A parcel that rattles when shaken is not ready to ship.

When should I split a shipment into two boxes?

Split as soon as one box feels hard to lift with one hand. Two lighter boxes cost little extra in effort and sharply cut the chance of a burst seam or a hurt back at either end. Splitting also keeps each parcel inside the 5 kg limit for a LetterAgent Xpresspost label in Canada. Label each box clearly, and if the books belong to one set, note the split on the outside or in a message to the recipient, so a missing second box is noticed right away. For a full shelf of books, plan on several small boxes from the start rather than one heroic carton.
