Biab online exists to support research work of all kinds. It provides bibliographic references - many with abstracts - covering all aspects of archaeology and the historic environment, and every chronological period, with a geographical focus on Britain and Ireland. There are almost 200,000 references from over three centuries of scholarship - with over 1,500 new records added each year.
Access is available to Digimap Ordnance Survey collection - registration required, Environment Digimap, Historic Digimap and Digimap OpenStream. Digimap allows users to view and create maps of any location in Great Britain using Ordnance Survey map data. Users can also download Ordnance Survey map data for use in other software packages, such as Geographical Information Systems (GIS), drawing software and CAD.
