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".

In the fourth era (1974–94), the "Britannica" introduced its 15th edition, which was re-organized into three parts: the , the , and the . Under Mortimer J. Adler (member of the Board of Editors of Encyclopædia Britannica since its inception in 1949, and its chair from 1974; director of editorial planning for the 15th edition of "Britannica" from 1965), the "Britannica" sought not only to be a good reference work and educational tool, but to systematize all human knowledge. The absence of a separate index and the grouping of articles into parallel encyclopaedias (the and ) provoked a "firestorm of criticism" of the initial 15th edition. In response, the 15th edition was completely re-organized and indexed for a re-release in 1985. This second version of the 15th edition continued to be published and revised until the 2010 print version. The official title of the 15th edition is the "New Encyclopædia Britannica", although it has also been promoted as "Britannica 3".
