Check out the Library of Congress Website!
The Library of Congress (LoC) was established in 1880 to support the research needs of the United States Congress. Over time, its mission and reach broadened, allowing it to serve as the nation’s library. As you can imagine this is quite an undertaking, making the LoC the largest library in the world! Early in this century the LoC began to digitize collections and put them online. Recently, I attended a webinar that provided a tour of features on the LoC website.
