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.
Meyers Blitz-Lexikon Meyers Blitz-Lexikon is a German print encyclopedia, now in the public domain. It was a concise single-volume version of the long-established "Meyers Lexicon". The name refers to the need for very rapid (Blitz = "Lightning") information. It was published to accompany the 15-volume version of the 7th edition of Meyers Lexicon. By limiting the explanations to a few keywords and making heavy use of abbreviations, a large number of entries were compressed into the single portable volume. Even complex topics were explained in just a few sentences. The volume contained eight plates, 2,481 illustrations in the text and 71 coloured panels, forming a 759-page lexicon with over 45,000 entries.
