BBIH provides bibliographic data on historical writing dealing with the British Isles, and with the British empire and commonwealth, during all periods for which written documentation is available – from 55BC to the present. As well as providing details of publications, the bibliography offers links to online catalogs to help you find the items in research libraries in Britain and Ireland. It also provides links to online text where available. The bibliography lists books, articles in books and articles in journals. Material is included irrespective of place or language of publication, although coverage is best for works published in Britain.
