Abstract:

One of the European Union’s vital tasks is to circulate and disseminate information in 11 languages. People are not generally aware of the scale and complexity of this task, and the ever-increasing amount and multilingual character of the documentation to be distributed, and it is only through continual development of the techniques used and constant rationalisation that the task can be accomplished each day. The Interinstitutional style guide has been produced with these things in mind.
