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".
Biographia Britannica
Biographia Britannica was a multi-volume biographical compendium, "the most ambitious attempt in the latter half of the eighteenth century to document the lives of notable British men and women". The first edition, edited by William Oldys (1696–1761) until his death, appeared in 6 volumes (the sixth in two parts, the second sometimes catalogued as volume 7) between 1747 and 1766. The editor of the two parts of volume 6 (1763 & 1766) is unknown. Five volumes of an incomplete second edition, edited by Andrew Kippis (1725–1795) with the assistance of Joseph Towers (1737–1799), appeared between 1778 and 1793, and cover names commencing Aa through to Fa; a sixth volume was prepared for publication, and may have been published, but now seems to be lost.
