London Street Listings in 1921.
The London historical street directory has now moved "permanently" to the new site - London19 - more may follow.
The problem with just a pub history site, which lacks any decent modern data; is that the site becomes more a local reference point for those specifically interested in a publican or licensee. This ignores the bigger picture of being a street directory using local pubs or churches as gps points. In fact, why would anybody want to track a map reference from their local church! Most people don't even know where this is.
