RES is an open data platform built by the BBC. The platform indexes and organises the digital collections of libraries, museums, broadcasters and galleries to make their content more discoverable, accessible and usable to those in UK education and research. Images, TV and radio programmes, documents and text from world class organisations such as The British Museum, British Library, The National Archives, Europeana, Wellcome Trust and the BBC are all being indexed by RES. The majority of the media indexed by RES is free to use for educational purposes.
The plugin searches the RES index, which is completely free to use. By default, only media which can be used by anyone are shown in search results. A user can optionally expand the search to include media which are restricted to particular groups of users (for example, Authorised users of BoB National who can access TV and radio broadcasts on demand).
