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".
Encyclopedia Nipponica
When it was founded in 1922, Shogakukan specialized in study books and magazines for elementary school students. According to its websites, 日本百科大事典 (Nihon hyakka daijiten) published in 1962 was the first encyclopedia from Shogakukan. Since then, Shogakukan has continuously published encyclopedias: 世界原色百科事典 (Sekai genshoku hyakka jiten) in 1965, 大日本百科事典ジャポニカ (Dainihon hyakka jiten japonica) in 1967, こども百科事典 (Kodomo hyakka jiten) in 1970, and 万有百科大事典 (Banyu hyakka daijiten) in 1972 among others. Shogakukan's "Encyclopedia Nipponica" has been one of the major Japanese encyclopedias. The other major encyclopedia, "Heibonsha World Encyclopedia" (世界大百科事典, Sekai daihyakka jiten), was published from Heibonsha. Since the foundation in 1914, Heibonsha has put emphasis on encyclopedias. Currently, "World Encyclopedia" holds three editions: "World Encyclopedia", "World Encyclopedia" on DVD, and the online edition called "Netto de hyakka".
