We encourage you to use local and online resources before reaching out to us with questions. Your local library is often able to respond to your question more quickly and is better equipped to identify resources locally available that will meet your needs.
If you have exhausted your resources locally, we can assist you through one of these methods:
- Ask A Librarian - our online reference request form.
- Phone
- Written correspondence
- Online chat available Monday – Friday, 12:00pm – 4:00pm (ET).
Please note that off-site security screening may cause delays in responding to written correspondence. For this reason, we recommend that you use the online Ask A Librarian services when possible.
You can find our general contact information on Contact. Reading room specific phone numbers are listed on each reading room's homepage. Online chat is accessible from the Ask a Librarian homepage.
Written correspondence can be directed to:
Library of Congress
