The objective of this publication is to provide a 'one stop' guide to business information, insofar as that is possible within the confines of a useable book. It aims to give guidance on both the published and organisational sources relevant to the needs of the non-professional business researcher and provides a listing of 'worthwhile' references and contacts. As previously, the Directory is organised so that both published sources and information centres are grouped together under their applicable Standard Industrial Classification (SIC) number and heading. This new edition also incorporates NACE classification and correlation tables. The second category again includes those UK and pan-national organisations which focus on specific, discrete industry sectors, which limits the number of organisational sources in the directory to those that are 'most worthwhile'.
