Encyclopædia Britannica Fifteenth Edition Macrophaedia Set

A set of twelve volumes from the Encyclopædia Britannica, specifically identified by the 'Britannica' name and the dark red and black binding scheme characteristic of the Fifteenth Edition, Macropædia section. The volumes are presented in a unified library binding, featuring a horizontal division with a deep burgundy or maroon lower section and a black upper section on the spine. The spines are embellished with gold-leaf or gilt lettering, including the title 'Britannica,' volume numbers 1 through 12, and alphabetical ranges displayed at the bottom of the red sections. Each volume displays a decorative gold thistle emblem at the top of the spine, a hallmark of the Britannica brand. The craftsmanship suggests a durable, mass-produced reference set intended for institutional or serious home library use, likely dating from the mid-1970s to the 1990s. The condition appears fair to good; while the spines show structural integrity, there is visible edge wear, slight scuffing on the corners, and minor fading of the gilt on certain volumes. This set represents the 'Knowledge in Depth' portion of the Britannica 3 system. The physical footprint of these twelve volumes suggests a heavy, large-format production using high-quality acid-neutral paper typical of premium reference sets from this era.
