London Metropolitan Archives holds the largest single collection of business archives held by a local authority in England and Wales. . . . The earliest business records date back to the fifteenth century. The records include management and financial series showing the changing fortunes of the companies, a vast array of production records with technological innovations illustrated through specifications, plans and photographs, rich sales, advertising and employment records.The guide is a comprehensive A-Z listing of company names and individuals for which substantive catalogued business records are held by the LMA. There are two associated indexes–a trade subject index and a geography index for sites where companies operated outside the United Kingdom. There is also an explanatory introduction.
For more information and to view the full guide, please consult the LMA Archives section on business and employment. There readers will also find links to the several other "information leaflets" that the LMA has published about specific aspects of its collections.
