The Library of Congress is the research library of the United States Congress, de facto national library of the United States of America, and the oldest federal cultural institution in the United States. Located in four buildings in Washington, D.C., as well as the Packard Campus in Culpeper, Virginia, it is the largest library in the world by shelf space and number of books. The head of the Library is the Librarian of Congress, currently James H. Billington.

The Library of Congress was instituted for Congress in 1800, and was housed in the United States Capitol for most of the 19th century. After much of the original collection had been destroyed during the War of 1812, Thomas Jefferson sold 6,487 books, his entire personal collection, to the library in 1815. After a period of decline during the mid-19th century the Library of Congress began to grow rapidly in both size and importance after the American Civil War, culminating in the construction of a separate library building and the transference of all copyright deposit holdings to the Library. During the rapid expansion of the 20th century the Library of Congress assumed a preeminent public role, becoming a "library of last resort" and expanding its mission for the benefit of scholars and the American people.

Christopher "Chris" Hillman (born December 4, 1944 in Los Angeles, California) was one of the original members of The Byrds, which in 1965 included Roger McGuinn, Gene Clark, David Crosby and Michael Clarke. With frequent collaborator Gram Parsons Hillman was a key figure in the development of country rock, defining the genre through his work with The Byrds, The Flying Burrito Brothers and the country-rock group Desert Rose Band.

Hillman, the third of four children, spent his early years at his family's ranch home in rural northern San Diego County, approximately 110 miles (180 km) from Los Angeles. He has credited his older sister with exciting his interest in country and folk music when she returned from college during the late 1950s with folk music records by The New Lost City Ramblers and others. Hillman soon began watching many of the country-music shows on local television in southern California at the time such as Town Hall Party, The Spade Cooley Show and Cal's Corral. Hillman's mother encouraged his musical interests and bought him his first guitar; shortly thereafter he developed an interest in bluegrass, particularly the mandolin. At age 15 Hillman went to Los Angeles to see the Kentucky Colonels bluegrass band at the Ash Grove, and later convinced his family to allow him to travel by train to Berkeley for lessons from mandolinist Scott Hambly. Around this time, Hillman's father died.

Steven Paul "Steve" Jobs (/ˈdʒɒbz/; February 24, 1955 – October 5, 2011) was an American businessman, designer and inventor. He is best known as the co-founder, chairman, and chief executive officer of Apple Inc. Through Apple, he was widely recognized as a charismatic pioneer of the personal computer revolution and for his influential career in the computer and consumer electronics fields. Jobs also co-founded and served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar.

In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. During this period he also led efforts that would begin the desktop publishing revolution, notably through the introduction of the LaserWriter and the associated PageMaker software.

Paul Frederic Simon (born October 13, 1941) is a grammy award winning American singer-songwriter, poet and guitarist.

Simon's international fame and success began as part of the duo Simon & Garfunkel, launched in 1964 with musical partner Art Garfunkel. Simon wrote most of the pair's songs, including three that reached No. 1 on the U.S. singles charts: "The Sound of Silence", "Mrs. Robinson", and "Bridge Over Troubled Water". The duo split up in 1970 at the height of their popularity, and Simon began a successful solo career, recording three highly acclaimed albums over the next five years. In 1986, he released Graceland, an album inspired by South African township music. Simon also wrote and starred in the film One-Trick Pony in 1980 and co-wrote the Broadway musical The Capeman in 1998.

Simon has earned 12 Grammys for his solo and collaborative work, including the Lifetime Achievement Award. In 2001, he was inducted into the Rock and Roll Hall of Fame and in 2006 was selected as one of the "100 People Who Shaped the World" by Time magazine. Among many other honors, Simon was the first recipient of the Library of Congress' Gershwin Prize for Popular Song in 2007. In 1986 Simon was awarded an Honorary Doctor of Music degree from Berklee College of Music where he currently serves on the Board of Trustees.

Woodrow Wilson "Woody" Guthrie (July 14, 1912 – October 3, 1967) is best known as an American singer-songwriter and folk musician, whose musical legacy includes hundreds of political, traditional and children's songs, ballads and improvised works. He frequently performed with the slogan This Machine Kills Fascists displayed on his guitar. His best-known song is "This Land Is Your Land." Many of his recorded songs are archived in the Library of Congress. Such songwriters as Bob Dylan, Phil Ochs, Bruce Springsteen, John Mellencamp, Pete Seeger, Joe Strummer, Billy Bragg and Tom Paxton have acknowledged Guthrie as a major influence.

Guthrie traveled with migrant workers from Oklahoma to California and learned traditional folk and blues songs. Many of his songs are about his experiences in the Dust Bowl era during the Great Depression, earning him the nickname the "Dust Bowl Troubadour." Throughout his life Guthrie was associated with United States communist groups, though he was seemingly not a member of any.
