Eur-Lex (stylized EUR-Lex) is an official website of European Union law and other public documents of the European Union (EU), published in 24 official languages of the EU. The Official Journal (OJ) of the European Union is also published on Eur-Lex. Users can access Eur-Lex free of charge and also register for a free account, which offers extra features.

Data processing of legal texts at the European Commission started way back in the 1960s, still using punch cards at the time. A system was being developed to capture relationships between documents and analyse them to extract and re-use metadata, but also to make retrieval easier.
Through the years, the system and its scope grew as the Commission started collaborating with other institutions of the European Union and as the Union started expanding. It was named CELEX (Communitatis Europae Lex) and soon became a well-used interinstitutional tool.
While initially used only internally, the system went through various degrees of availability to the public, including offering content under commercial licences via private companies. Finally, in 1997 a web version was launched and named Eur-Lex, hosted by the Publications Office of the European Union.
The Eur-Lex website was opened to the public in 2001, while CELEX still existed as a separate database until the end of 2004. Subsequently steps were undertaken to merge the two services and to make them completely free of charge.
With the accession of new countries to the European Union and advancements in web and data-processing technologies, the system needed to be improved. A new version was launched in 2004. In 2014 the website saw another major overhaul, including a new database called "CELLAR".
An aligned parallel corpus consisting of 3.9 million Eur-Lex documents in 24 languages, ranging in size from 37 million tokens for Irish to 840 million tokens for English, was produced in 2016 and made available in the Sketch Engine. Unannotated data is provided to researchers under a Creative Commons license. At the time of publication, the authors considered the Eur-Lex Corpus the largest parallel corpus built from European language resources, more suitable for linguistically motivated searches than the Eur-Lex official website.
On Eur-Lex users can access documents in the official EU languages. Language coverage depends on the date of the accession of a country to the EU. All EU law in force on the date of the accession of a new Member State is available in the language of the acceding country as are all documents adopted after this date. Documents repealed or expired before the date of accession are not available in the language of the acceding country.
While each document (and each language version) is an individual part of the database, the content is grouped into sectors. There are currently 12 sectors, each represented by a number or a letter:
|1 - Treaties||2 – International agreements||3 – Legislation||4 – Complementary legislation|
|5 – Preparatory acts||6 – Case-law||7 – National implementing measures||8 – References to national case-law concerning EU law|
|9 – Parliamentary questions||0 – Consolidated legislation||C – Other documents published in the Official Journal C series||E – EFTA documents|
Official Journal of the European Union
In 1998 the Official Journal of the European Union (OJ) started being published online, on Eur-Lex. As of 1 July 2013, the digital version of the Official Journal bears legal value instead of the paper version, which is now printed on demand only. The e-OJ has an advanced electronic signature which guarantees its authenticity, integrity and inalterability.
Eur-Lex contains all EU law (sectors 3 and 4), which can be retrieved by browsing or using the search options. The main types of acts under this heading are EU treaties (sector 1), directives, regulations, decisions as well as consolidated legislation (sector 0), etc. Consolidation is the integration of a basic legal act and all of its successive amendments and corrigenda into one easy-to-read document. Consolidated texts are intended for use as reference and have no legal value.
Preparatory acts and legislative procedures
The database contains also documents preceding legal acts, such as legislative proposals, reports, green and white papers, etc. (sector 5). Some proposals never make it past the preparatory stage, but are still available for consultation.
Each legislative procedure is presented in Eur-Lex with a timeline and a list of events and pertaining documents. Procedures can be accessed via the search or from one of the procedure documents.
EU case law
Eur-Lex stores also international agreements (sector 2), parliamentary questions (sector 9), EFTA acts, which include also acts by the EFTA Court and by the EFTA Surveillance Authority (sector E); judgments delivered by courts in contracting states and the EU Court of Justice under the Brussels Regime; references to national case law concerning EU law (sector 8) and other public documents.
CELEX number and other identifiers
While EU documents are numbered in different ways, each of them is assigned a unique, language independent identifier, a CELEX number.
This identifier is composed of the number of the sector, then 4 digits for the year, then one or two letters for the type of document and finally 2-4 digits for the number of the document. For example, the CELEX number of the Waste Electrical and Electronic Equipment Directive is 32012L0019 (3 is the sector, legislation; 2012 is the year of publication in the OJ; L represents EU directives and 0019 is the number under which the directives was published in the OJ).
The European Case Law Identifier (ECLI) was introduced by the Council, which concluded that for "identification of judicial decisions a standard identifier should be used which is recognisable, readable and understandable by both humans and computers". Documents can be retrieved using ECLI also on Eur-Lex.
Documents can be retrieved via a search engine (IDOL by HP Autonomy) using various search forms. It is possible to search by document references, dates, text and a multitude of metadata. Registered users have the option of using the expert search and performing searches using Boolean operators.
Text display and formats
Texts and their metadata can be retrieved, displayed and downloaded in various formats (html, pdf, xml). For simultaneous work with several language versions, users can use the multilingual display, which is especially useful for translation and linguistics .
Reuse of data
The data is available for reuse via a web service for commercial or non-commercial purposes as long as the source is acknowledged. Certain collections (datasets) of documents found on Eur-Lex can also be found on the European Open Data Portal.
Saved documents and searches
Registered users have access to a plethora of settings with which they can customise their experience on the website.
|Functionality||Non-registered users||Registered users|
|Simple and advanced search||YES||YES|
|Expert search (Boolean operators, more options)||NO||YES|
