Orchestral sets coverage
Orchestral material that was notified to the British Union Catalogue of Orchestral Sets (BUCOS) formed the core of the orchestral collection, with later amendments notified to the British Library.
Orchestral material that is only available from the publisher
Users should be aware that much modern copyright material is only available on hire from the relevant publisher. A work probably remains in copyright If the composer, or the author of any text that was set died more recently than 70 years ago – dates can usually be found online. If such a work does not appear in Encore21, this probably means that the work remains in copyright. Information on publishers' hire libraries may be found on the database Zinfonia, though not all publishers are represented there so you might need to contact the publisher directly. Though copies might be available from other sources, you should be aware that their unauthorised use for performance in the UK is likely to infringe copyright, and might lead to penalties.
Vocal sets coverage
Public library collections in England, Scotland and Wales that are known to lend performance sets.
