Everything here is already in order.

The short run nearest the door. Heavy traffic, heavier rebinding: four volumes here carry replacement spines cut in-house, which is why the labels sit a centimetre low.

Three classes share this range because the 200s no longer fill a bay of their own. The shelf-reader's note in the margin: “200s drifting right — reshelve before the 305s arrive from acquisitions.”

The longest continuous run in the west stacks and the only one that spans two bays without a break. Oversize volumes are laid flat at the far end rather than shelved upright, which is why the last board reads short.

The window range. Spines here fade fastest, so the 700s rotate with closed storage every eighteen months — check the label date before assuming a gap is a loss.
