Encyclopædia Britannica The Encyclopædia Britannica (Latin for "British Encyclopaedia"), published by Encyclopædia Britannica, Inc., is a general knowledge English-language encyclopaedia. It is written by about 100 full-time editors and more than 4,000 contributors, who have included 110 Nobel Prize winners and five American presidents. The 2010 version of the 15th edition, which spans 32 volumes and 32,640 pages, was the last printed edition; digital content and distribution has continued since then.
Century Dictionary The Century Dictionary and Cyclopedia was one of the largest encyclopedic dictionaries of the English language. The first edition was published from 1889 to 1891 by The Century Company of New York, in six, eight, or ten volume versions (originally issued in 24 fascicles) in 7,046 pages with some 10,000 wood-engraved illustrations. It was edited by Sanskrit scholar and linguist William Dwight Whitney, with Benjamin Eli Smith's assistance. It was a great expansion of the smaller "Imperial Dictionary of the English Language", which in turn had been based on the 1841 edition of Noah Webster's "American Dictionary".
