108 livery companies have operated in London. Wikipedia maintains a list of The City Livery Companies, along with links to company websites.
The Livery Companies Database is a helpful resource that supplies contact details for each active company.
Histories have been written on many London livery companies. The British Library has compiled a detailed list.
Apprenticeship records are one of the most valuable genealocial sources created by London livery companies. They often name the following information about an apprentice's father: name, residence, and occupation. Cliff Webb has abstracted the records of many companies:
