|Postcard of the Library of Congress in 1902 from the New York Public Library Digital Collections|
Today, the Library of Congress is still an "unparalleled world resource" which houses over 158 million items in three buildings. They also provide services and resources for librarians and libraries around the country, including the Tarleton Libraries. We rely on the Library of Congress classification system to organize our collections, and obtain catalog records written by Library of Congress catalogers. The Library of Congress also houses the United States Copyright Office, which gives official guidance on copyright law. In short, it has grown a lot from the $5,000 worth of books originally appropriated by President Adams!
