The Library of Congress encourages
researchers to use local library resources first. Your local library will often be able to respond to your query more quickly than the Library of Congress, and is better able to identify and respond to your specific and ongoing needs. In many cases, you will find that the information you need is available at your local library. Once you have exhausted local and regional resources, you may direct specific enquiries to the Library of Congress by writing a letter or sending an email to one of the addresses given below. Before sending an enquiry to the Library, consult the About the Library FAQ or the Research
and Reference FAQ pages; the answer to your question may be listed there. Your enquiry should explain what resources you have already consulted, and include a surface mail address. The Library refers telephone reference questions to local libraries, which in most cases will have the resources to answer those questions. Due to time and staff constraints, the Library of Congress is not able to undertake extensive research projects; a list of certified researchers who will do such projects for a fee is available from the Humanities and Social Sciences Division.
