The use of ‘viz.’ should be avoided. Use ‘namely’. The abbreviation ‘cf.’ is acceptable and should not be changed to ‘see’.

Always use ‘Heads of State or Government’, not ‘Heads of State or (and) of Government’, or any other forms.

Use a hyphen after ‘non’ as in ‘non-compulsory’.

Note the difference:

Ministry of … but Minister for …

Numbered paragraphs and points are printed close up and in parentheses after the article number; unnumbered items come before the article number:

The third indent of the second subparagraph of Article 2(1) of Regulation No …

Avoid abbreviating Article to ‘Art.’ in running text. Avoid using the § sign, which means ‘section’ in English, but ‘paragraph’ in other languages.

Always use a full point on the line as a decimal point. Exceptions to this may be made for multilingual publications, statistical works, works where the tables are composed once for all language versions — for these exceptions a decimal comma is acceptable. The UK and Irish authorities agreed that the decimal comma should be used in all English-language editions of the Official Journal (starting from 1 March 1983).

Administrative units: use the form Human Resources and Security DG, A.7.
