In January 2010 about 120,000 records for around 155,000 books held in the National Trust’s 140 historic libraries became publicly available for the first time via the web catalogue Copac.
Copac provides free access to the merged catalogues of around 70 UK and Irish academic and specialist research libraries, including the British Library and the national libraries of Scotland and Wales.
