The object of this volume is to provide scholars undertaking research in the history of British economic thought with a systematic listing of the available sources of manuscript material. It is the first work of its kind, and is based on extensive search inquiry into the scattered public and private sources of personal papers and correspondence of British economists. Over one hundred and fifty listings are printed here. They include numerous lesser figures as well as the most distinguished contributors to the varied literature of economics in the period since 1700. The Guide should, therefore, be of interest not only to specialist historians of economics but also to those concerned with the wider role of economic ideas in political debate and the formation of public opinion.
