Encyclopædia Britannica
The "Britannica" is the English-language encyclopaedia/encyclopedia that was in print for the longest time: it lasted 244 years. It was first published between 1768 and 1771 in the Scottish capital of Edinburgh, as three volumes. (This first edition is available in facsimile.) The encyclopaedia grew in size: the second edition was 10 volumes, and by its fourth edition (1801–1810) it had expanded to 20 volumes. Its rising stature as a scholarly work helped recruit eminent contributors, and the 9th (1875–1889) and 11th editions (1911) are landmark encyclopaedias for scholarship and literary style. Beginning with the 11th edition and following its acquisition by an American firm, the "Britannica" shortened and simplified articles to broaden its appeal to the North American market. In 1933, the "Britannica" became the first encyclopaedia to adopt "continuous revision", in which the encyclopaedia is continually reprinted, with every article updated on a schedule. In March 2012, Encyclopædia Britannica, Inc. announced it would no longer publish printed editions, and would focus instead on "Encyclopædia Britannica Online".
History of the Encyclopædia Britannica
Sales figures for the 11th edition were comparable to those of the 9th, which sold hundreds of thousands of copies including the unlicensed sets. Unlike the 9th, however, the 11th edition was not infringed, all sets being printed legitimately by Britannica. It can be seen that the 9th and 11th editions were massively better-sellers than previous editions. This is mainly due to the increase in population of, and sales in, the United States, which were mere colonies with low population when Britannica started out in 1768.
