摘要:The paper attempts to document the ratio in the temporal and local contexts between the ‘literary’ languages used in the books printed in Bohemia,Moravia and Silesia in the second half of the 18th century,that is the national/ethnic languages German and Czech (and exceptionally others),and supranational Latin. The analysis is based on data obtained by statistical evaluation of research in the National Library in Prague and the Scientific Library in Olomouc (the data from the two collections were merged,duplicated,some items unsuitable for methodological reasons were removed,and the aggregate was hand-sorted and categorised). Five pieces of research were conducted on the Czech literary production in each decade,1751,1761,1771,1781,and 1791 (the average number of titles in each study is around two hundred),and another study served to compare the acquired data with the situation in a more remote period in 1701. The author determines the ratios between German,Czech and Latin in the book production as follows: 1) In relation to the time when a book was published;here the author attempts to relate the statistical data to well-known cultural-historical and linguistic facts. 2) In relation to the place or publisher — here the focus is on a comparison between the linguistic aspects of the production in and outside Prague (Hradec Králové,Kutná Hora,Olomouc,Slovakia)..
