British History Online
British History Online is a digital library containing some of the core printed primary and secondary sources for the medieval and modern history of the British Isles. Created by the Institute of Historical Research and the History of Parliament Trust, BHO aims to support academic and personal users around the world in their learning, teaching and research.
BHO is an online source of the complete Survey of London.
Previously ECA Library only stocked the volumes for Knightsbridge, Isle of Dogs, and County Hall. Now you can search all the volumes of this key resource by searching on BHO, here: http://www.british-history.ac.uk/browse.aspx
