English Abstract: 

"Thema is intended for use by all parts of the book trade: unlike other book trade subject classifications, it aims to be globally applicable. And in contrast to various library classifications that are used internationally, it is tailored for commercial use within the trade. It is a flexible standard that allows each market to retain its unique cultural voice while still presenting a unified subject hierarchy that rationalises book classification. The goals of Thema are to reduce the duplication of effort required by the many distinct national subject schemes, and to eliminate the need for scheme-to-scheme mapping that inevitably degrades the accuracy of classification, by providing a single scheme for international use. It can be used alongside existing national schemes like BIC, BISAC, WGS or CLIL, and has the potential to eventually replace them (though this is not an immediate goal)."
