Many resources are freely available to Londoners if they only knew where to look, so Libraries & Learners in London has developed this section of the web site to provide guidance on some of these "hidden" resources. It should help you to identify the most useful sources of information and provides links to relevant web pages where they exist.
European Information suggests a range of sources of European Community information in London appropriate to your needs
Local Studies if you wish to know more about your locality, then your local authority archive or museum may be the best place to start!
In addition the subject specialisms of London public libraries can be found on the London Libraries Collections page and other collections and online databases, some available remotely can be found here
