The 'Guide to Business Archives: Unlock the riches of the archives of London commerce and trade with the world' is a comprehensive A-Z of company names and individuals for which substantive catalogued business records are held by the London Metropolitan Archives. There are two associated indexes – a trade subject index and a geography index for where companies operated outside the UK. There is also an introduction to how the guide works.
