What is an open back vs. closed back bookcase?

An open-back bookcase has no back panel, allowing books and items to pass through (useful as a room divider) and making installation against existing wall treatments easier. A closed-back bookcase has a full back panel — typically 1/4 in. hardboard — that prevents items from falling through, provides structural rigidity, and gives a finished appearance.
