 In 1816, Bell's trustees sold the rights to the "Britannica" for 14,000 pounds to Archibald Constable, an apprentice bookseller, who had been involved in its publication from 1788.To secure the copyrights for the 3rd edition supplement, Constable gave Bonar a one-third stake in the "Britannica"; after Bonar's death in 1814, Constable bought his rights to the "Britannica" for 4,500 pounds sterling.Being a reprint of the 4th, set in the same type, Encyclopædia Britannica's 5th edition was one of the last publications in the English language to use the long s in print.
