What is LERU?

The League of European Research Universities (LERU) is a consortium of some of the most renowned research universities in Europe. Founded in 2002, as a partnership of 12 leading multi-faculty research universities, it expanded its membership to 21 universities in 2010.

What is the LERU Law Portal?

The LERU Law Portal allows you to discover the research undertaken in the law departments of 12 of Europe's leading universities.

You can search over 46000 records and, where they have been made available, the full text of articles, chapters and other scholarly outputs.

You can see which universities have contributed to the portal via the browse by institution.

Searching the portal

To undertake a keyword search, click on the 'Search' link, found on the Portal navigation bar, or use the search box located in the left column. Enter keywords in the search box and click 'Search'. All fields in the LERU Law database are searched.

Search Techniques

  • Use * as a wildcard to match any sequence of characters: e.g. comput* would match computer, computing, computerised, computational, etc.
  • Search terms are linked with 'AND' by default.
  • Use OR to broaden your search, e.g. Sweden OR Sverige.
  • NOT may be used to exclude a word from your search results, e.g. nebula* not andromeda
  • Use quotes to search for exact phrases, e.g. "genetic algorithm"
  • Parentheses may be used to create more complex queries, e.g. (Sweden or Sverige) and economics

Accented Characters:

To help searchers, the LERU Law Portal makes accented characters searchable as if they were unaccented, and vice-versa. For example, searching for either
Mexico or
should produce exactly the same number of hits.

Non-Western scripts:

Thesis details in non-Western character sets are not transliterated by LERU, but they are retrievable through searches in those character sets. Where accompanying transliterations / translations are provided to LERU, both Western and non-Western versions are made searchable.


This feature allows you to browse records harvested by the LERU Law Portal by awarding institution (where known), year of award or country. Select an index to browse and follow the links to the theses which interest you.

Search History

The LERU Law Portal stores your search history, allowing you quick access to the results of previous searching and browsing. You can view these through the Search History tab. The search history is available for the duration of your session. It will be removed after 20 minutes of search inactivity.


LERU Law results are shown by default in a brief summary format, which gives basic information about each thesis: the author and title, the date of award, the awarding institution, and the document type.

To progress to the full LERU record for any thesis, and to access a copy of the thesis, click the title. The full display shows all the details collected about the thesis by LERU, in exactly the format in which they were received. Clickable links to publicly accessible copies of the thesis will appear in this display.

Marked List

As you search the Portal, you may mark records which are of interest and add them to a list. To mark records from a results list, use the checkbox in the left-hand column. From a full record, use the 'Add to marked list' button.

To access your list, use the 'Marked List' tab. From here you may send a copy of the list to a specified email address in a choice of brief or full formats.

Note that your marked list is only accessible for the duration of your search session. It will be removed after a period of 20 minutes of search inactivity.
