Official Journal reference

The main source for EU legislation is the Official Journal of the European Union (OJ), which comprises two series:

  • L series - official source for EU legislation
  • C series - information and notices.

Older treaties were published in the C series. Most legislation is now published in the L series (with the exception of the Lisbon Treaty).
