Research Libraries UK
Research Libraries UK (RLUK) (formerly CURL) comprises 32 university libraries, 3 national libraries, and the Wellcome Collection in the United Kingdom and Ireland. Its aim is to increase the ability of research libraries to share resources among themselves. The holdings of these libraries provide the basis of the Copac online catalogue.

The Consortium of University Research Libraries (CURL) started in 1983 as an informal grouping of the seven largest university research libraries (the university libraries of Cambridge, Edinburgh, Glasgow, Leeds, London, Manchester, and Oxford) to "explore the possibilities of closer co-operation, particularly, but not exclusively in the use of automation". The consortium was incorporated as a company limited by guarantee in 1992. By April 1997 the number of full members had increased to 20, including Trinity College Dublin in the Republic of Ireland, and the three national libraries of the UK and the Welcome Institute for the History of Medicine had been admitted as associate members. The increased size of the organisation led to the appointment of the first full-time executive secretary in 1997.

In 2011, Queen's University Belfast joined as RLUK's 30th member, meaning that all 20 then-members of the Russell Group of universities were now members. Of the four universities that joined the Russell Group in 2012, Durham and York were already members of RLUK, having joined in 1996 and 2011 respectively, while Exeter and Queen Mary, University of London joined in 2012 and 2014.
