ISG website PDF: new edition
A new PDF edition of the Interinstitutional Style Guide is available, reflecting the content of the website as at 19 April 2022. The PDF can be downloaded for free from the EU Publications portal.

Modernisation of the website
This autumn, the style guide will be available in a new environment. Because of the ongoing work to modernise the ISG, it has been decided, in agreement with the Steering Committee, that only essential updates to the content will be carried out until the new website is released. Thank you for understanding.

This website is available in the 24 official languages of the European Union. All language versions follow the same layout structure (except for Part Four). Thus, using the language drop-down menu at the top right of the page you can find the corresponding page in the language of your choice.
