Welcome to the online application of the electronic lexicon of the ISSMGE. The first version of the electronic Lexicon was released on March 2013. The current version includes the translation of 1592 terms in 14 languages. A large number of professionals have been involved in the digitization of the 1981 printed version of the Lexicon and its expansion with more languages in this version. They are acknowledged in the "Acknowledgements" tab of the application. Country members interested in translating the lexicon terms in an additional language are encouraged to contact ISSMGE. Please use the "Feedback" tab, to recommend any improvements on the Lexicon, additional words, or report any errors.
