About us

What is Copac?

Copac exposes rare and unique research material by bringing together the catalogues of over 100 major UK and Irish libraries (and growing). In a single search you can discover the holdings of the UK’s national libraries (including the British Library), many University libraries, and specialist research libraries.  Researchers and educators use Copac to save time in their research, to quickly and easily discover and locate resources, to check document details, review materials in their field, and assess the rarity of materials etc. Information professionals trust Copac to give them access to a unique pool of high-quality bibliographic information.

Searching Copac means you are searching a wide and varied range of library catalogues, from the collections of the Oxford and Cambridge universities to the libraries at the National Trust and the Royal Botanic Gardens Kew. Copac’s contributors run the gamut from conservatoires to the catalogues of the major Russian and East European Collections in the country. We are adding more libraries all the time with a focus on specialist research collections, for example the Middle Temple Library and Institution of Mechanical Engineers Library, increasing the visibility of a growing range of specialist and rare materials.

The Copac team consult with librarians and users in order to develop the service, and regularly engage with our key stakeholders such as RLUK, Jisc Innovations, CILIP, and other strategic bodies. Many of Copac’s new features are as a result of user feedback. For example, as a result of talking with information professionals, we know that Copac is used in the daily routines of many libraries, facilitating work in a variety of different functions, including cataloguing and inter-library loan.

System Maintenance

Routine System maintenance is scheduled for three times a year:

  • Betweeen 08.00-09.00 on the first Tuesday of April, August and December.

During this time the service is likely to be unavailable for a minute or two. It may also affect your ability to login via Shibboleth for a few minutes.

We expect all work to be complete before 09.00.


  • Copac is a Jisc service, provided for the UK community on the basis of an agreement with RLUK. The service uses records supplied by RLUK members, as well as an increasing range of specialist libraries with collections of national research interest. A full list of contributors is available on our Libraries page.
