The University of Hull have introduced an alternative interface to their library catalogue, which will sit alongside the current interface. The direct link is http://blacklight.hull.ac.uk. This interface is based on the Blacklight discovery platform developed by universities in the US specifically for academic library catalogues and design concepts used by Twitter, adapted for catalogue use.
University of Hull Library is keen to gather feedback on the new interface, so please try it out and let them know what you think.
Further information on the Blacklight interface, including details of features and tasks to be done, can be found via the FAQ on the site (see http://blacklight.hull.ac.uk/faq).
