In many cases, you will find that the information you need is available at your local library. 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.
Public libraries are often listed in the government section ("blue pages" in the U.S.) or business section ("yellow pages") of your local telephone book. You may also use these Internet resources to find libraries by name or location:
