Billington, who was sworn in on September 14, 1987. - How does Congress use the Library?
Thousands of requests are received annually by the Congressional Research Service (CRS), one part of the Library that directly serves Congress.

Another department of the Library that works closely with Congress is the Law Library. With collections in foreign, international and comparative law, it serves as the foreign law research arm of Congress. - What are the top priorities of the Library at this time?
First, to make knowledge and creativity available to the U.S. Congress on a continuing basis. Second, to acquire, organize, preserve, secure and sustain for the present and future use of Congress and the nation a comprehensive record of American history and creativity and a universal collection of human knowledge. The Library's third priority is to make its collections maximally accessible to Congress, the government and the public through such means as its website. Its fourth priority is to add interpretive and educational value to the basic resources of the Library to highlight the importance of the Library to the nation's well-being and future progress. - How many visitors does the Library serve?

After its founding in 1800, the Library was housed in a boarding house and later in the Capitol. Its first permanent building — now called the Thomas Jefferson Building — was opened in 1897. The John Adams Building was completed in 1939 and the James Madison Memorial Building in 1980. - Who designed the Jefferson Building and how much did it cost?
Its construction was based on a design, submitted in competition, by architects John L. Smithmeyer and Paul J. Pelz. The building cost almost $6.5 million, $150,000 less than expected. The building officially reopened to the public in May 1997 following some 12 years of renovation, with a new Visitors' Center and special area studies reading rooms for use of foreign language collections. - Who were the artists for the Jefferson Building?

The Library uses the full range of traditional methods of conservation and binding as well as newer technologies such as the deacidification of paper and the digitization of original materials to preserve its collections. These measures include maintaining materials in the proper environment, being prepared for emergencies such as water leaks, ensuring the proper care and handling of the collections, and stabilizing fragile and rare materials by placing them in acid-free containers to protect them from further deterioration. - How is the Library using new technologies?
The expanded Computer Catalog Center adjacent to the Main Reading Room enables patrons to use a simplified automated bibliographic search program to look up titles in the Library's general book collections. Users outside the Library can gain free access to its online catalog. Major exhibitions of the library are also available online, as are selected prints and photographs, historic films and political speeches. Information about the U.S. Congress can be found online at THOMAS, and the Library has recently launched an app that allows users access to the Congressional Record on their iPads. - Who can use the Library and check out books?
