The Official Journal was published for the first time on 30 December 1952 as a single series (A). In April 1958 the A series was replaced by the P series. The P series existed from 1958 until 1967. Since January 1968 the OJ has been published in two separate series, L (Legislation) and C (Information and Notices). Since 1998, an electronic version has been made available on EUR-Lex with every printed edition. All Official Journals are now being scanned and gradually uploaded to EUR-Lex in PDF format.
