This database contains a searchable catalogue
of the entire business information collection held in the British Library’s Business & IP Centre. Although you cannot access the information itself from outside the Library, this resource allows you to find out exactly what is available. This powerful tool is perfect if you know what you are looking for, though if you aren't sure then either the Business & IP Centre website
or one of the Library's industry guides
might be a better place to start.
The collection is divided up into four main sub-sections: market research; company information; trade directories; and journals. Between these, it should be possible to gain an excellent overview of the market
you wish to serve and the industry
in which you hope to compete.
