Multi-volume supplements were issued to the fourth, fifth, and sixth editions as a group, within the Britannica's first era managed by its founders and Archibald Constable.
The Encyclopædia Britannica has been issued in 15 editions, with multi-volume supplements to the third edition and to the fourth, fifth, and sixth editions as a group. This supplement programme belongs to the first era (1768–1824), when the Britannica was managed and published by founders Colin Macfarquhar and Andrew Bell and by Archibald Constable. Macvey Napier edited the Supplement to the Fourth, Fifth, and Sixth Editions. No supplied passage states a publication date for the sixth edition itself; 1820 is a legacy placeholder.
