Contains a gazeteer of streets, various old maps, a list of old newspapers, all kind of statistics about health and poverty, articles about local governance and architects who helped make Brighton how it looks today, and much more. If you have access to the census and want to browse by street rather than look up a person, they also have helpful schedules of Brighton enumeration districts here.
