What is a box-style vs. frame-style bookcase?

A box-style bookcase uses solid side, top, and bottom panels as the structural shell — the most common commercial design. A frame-style bookcase uses exposed structural posts with thin panel inserts, giving a more open, architectural look. Box-style is more storage-efficient; frame-style is more visually distinctive.
