The listing of beer retailers in 1914 in the many trade directories is a useful guide to the London street directories. Many of these beer retailers / publicans are just off licences. Others are the pre-requisite of the modern Pub as we know it today.
Here are a few (about a thousand publicans). They are all listed by address only, but you may find a 'pub sign name' has been added in the census, which makes this more appealing.
