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".

The 15th edition had a three-part structure: a 12-volume of short articles (generally fewer than 750 words), a 17-volume of long articles (two to 310 pages), and a single volume to give a hierarchical outline of knowledge. The was meant for quick fact-checking and as a guide to the ; readers are advised to study the outline to understand a subject's context and to find more detailed articles. Over 70 years, the size of the "Britannica" has remained steady, with about 40 million words on half a million topics. Though published in the United States since 1901, the "Britannica" has for the most part maintained British English spelling.
