In Germany, practical reference works intended for the uneducated majority became popular in the 18th century. The Marperger Curieuses Natur-, Kunst-, Berg-, Gewerkund Handlungs-Lexicon (1712) explained terms that usefully described the trades and scientific and commercial education. Jablonksi Allgemeines Lexicon (1721) was better known than the Handlungs-Lexicon, and underscored technical subjects rather than scientific theory. For example, over five columns of text were dedicated to wine, while geometry and logic were allocated only twenty-two and seventeen lines, respectively. The first edition of the Encyclopædia Britannica (1771) was modelled along the same lines as the German lexicons.
