The new Bibliography of British and Irish History (BBIH) is now available for trial usage. Previously known as the Royal Historical Society Bibliography the new Bibliography is a joint-venture between the RHS, the IHR and the publisher Brepols. The existing editorial team, with its close links to academic historians, will continue to be involved. Our aim is to maintain and to improve upon the standards and facilities of the current Bibliography and, importantly, to keep the Bibliography up-to-date by adding information about new publications, which currently entails adding around 10,000 record each year. BBIH will be available by institutional and individual subscriptions, and we hope that our existing users will be able to access it. You can help by telling your library about the changes and encouraging them to subscribe to BBIH. For users and members of the IHR the trial version is available for use at the IHR and we welcome feedback. The new Bibliography will be launched on 1st January 2010, when the existing RHS Bibliography website will close.
