With the publication of its “Recommendations for Terminology Work”, COTSOES intends to create a basis for international co-operation, as all the participating services are well aware that without this it would be impossible to keep up with the rapid development of specialised vocabularies. COTSOES wishes to promote such co-operation by pooling experience in the terminology work of state administrations and by demonstrating the proven requirements of terminological working methods that ensure that the work of many different services can be put together to form a whole that will be of benefit to all.
