We have got a trial of The Bibliography of British and Irish History Online (BBIH).  This resource has grown out of, and will supersede, the Royal Historical Society Bibliography of British and Irish History. This is a database of around 470,000 records, updated 3 times per year, with around 10,000 references added annually.
It covers British and Irish history and relations with the empire and Commonwealth, from 55 BC to the present. The bibliography lists books, articles in books, and articles in journals. This resource can be accessed via the library catalogue
