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".
Encyclopædia Britannica Eleventh Edition
Originally, Hooper bought the rights to the 25-volume 9th edition and persuaded the British newspaper "The Times" to issue its reprint, with eleven additional volumes (35 volumes total) as the tenth edition, which was published in 1902. Hooper's association with "The Times" ceased in 1909, and he negotiated with the Cambridge University Press to publish the 29-volume eleventh edition. Though it is generally perceived as a quintessentially British work, the eleventh edition had substantial American influences, not only in the increased amount of American and Canadian content, but also in the efforts made to make it more popular. American marketing methods also assisted sales. Some 14% of the contributors (214 of 1507) were from North America, and a New York office was established to coordinate their work.
