About Library Hub Discover

Jisc Library Hub Discover exposes rare and unique research material by bringing together the catalogues of major UK and Irish libraries. 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. This service replaces Copac and SUNCAT, providing access to a growing range of library catalogues, with a new interface style and updated search facilities, with more changes in the pipeline.

Library Hub Discover is one of three services built on the Jisc National Bibliographic Knowledgebase, a growing collaboration with an increasing number of libraries contributing to the shared database, to benefit the academic and broader research community as well as local library activity and developments. The other services are:

  • Library Hub Compare: Collection analysis service for library staff in Jisc member libraries and other NBK contributors. For more information see Library Hub Compare.
  • Library Hub Cataloguing: Shared cataloguing service for library staff in Jisc member libraries and other NBK contributors.
    For information about Library Hub Cataloguing, including Terms of use, see About Library Hub Cataloguing.

Service Features

See our video introduction to the service.

The Discover service provides the foundations on which we will continue to grow. Features include:

  • A single search box that allows keyword searching as well as the ability to generate complex Boolean queries. Details are given in the Search Help
  • An advanced search providing detailed options for defining a search, including searching for maps and music
  • Location searching eg. for materials within a particular region, or for individual institutions and their branch libraries.
  • A wide range of contributing libraries, with increasing numbers of UK university contributors and specialist research collections

We are continuing to work on the Discover service across a number of areas. We are continuing to work with more academic and specialist libraries to load additional catalogues and ensure regular updating is established where appropriate. Some specialist collections are static and regular updating is not required. And we are working to introduce new interface feautes as part of ongoing service developments, as well as in reponse to requests from service users. We review all the feedback we receive and use that to help us focus our development activity.

Record errors and problems

Book cover images

If you notice a problem with the book cover image being displayed in any records you can report this through the Jisc helpdesk (help@jisc.ac.uk). We will investigate to see why it's happening. The cover images come from an external supplier, so we will pass on details of the problem but we cannot resolve it directly.

Removal of a book cover image

If there is a book cover image displaying in Library Hub Discover that you think needs to be removed for copyright reasons then you can report this through the Jisc helpdesk (help@jisc.ac.uk). We will contact our image supplier to discuss the issue you have raised and the image may be suppressed whilst we do so.

Errors in the records

All the records in Library Hub Discover are supplied and updated by our contributing libraries. We do not amend the records, because any changes we made would be over-written when we next received an update or reload from the library. So any errors or other data problems need to be reported to the originating library. If the library chooses to change the record in their local catalogue, we will then receive the updated version of the record in the library's next update, which will correct the record in Library Hub Discover.

A Library Hub Discover record may have been created by merging records from multiple contributing libraries. In this case an error is often only present in a few of the original records. To check which libraries you need to contact, in the Result screen select a library name to see the Holdings Display, which shows the record supplied by that individual library, allowing you to see if it contains the error. You can use the list of libraries on the right of the Holdings screen to move between the individual library Holdings displays associated with that record.

You can find contact details for all our contributing libraries via our Libraries page. Select the name of a library to see their information page, including contact information.

If you find an error that doesn't seem to occur in any of the individual library records shown in the Holdings display, please let us know and we will investigate the source of the problem. You can contact us via the Jisc Helpdesk help@jisc.ac.uk.

Removal of a record

If there is a record in Library Hub Discover that you think needs to be removed then you need to contact the libraries that hold the document in question. If those libraries choose to remove the document from their collection they will delete the record from their local catalogue. After which we will receive a deletion record in their next update and the record will be removed from Library Hub Discover.

You can find contact details for all our contributing libraries via our Libraries page. Select the name of a library to see their information page, including contact information.
