The 3,600 square foot facility is a wing of Walker’s home in Ridgefield, Connecticut. It contains about 30,000 books as well as maps, charts, artworks and a wide variety of museum-level artifacts. It is not open to the public.
Architecture and Art
The Library was constructed in 2002 to house and showcase a collection of books and artifacts that Walker had been assembling for twenty years.
Designed by architect Mark P. Finlay  and owner Jay S. Walker, the room combines traditional architecture with floating platforms, multiple stairways, and a glass bridge. The bridge connects the entryway at the middle of three levels. Sound and lighting were designed by artist Clyde Lynds. A series of illuminated, etched glass panels, approximately 3 feet tall x 4 feet wide, are used as part of the railings around the stairs and platforms. Each of the nearly 200 etched panels depicts, in symbolic form, one of the seminal inventions of human history.
Items on display at the Walker Library include an original 1957 Russian Sputnik, the world’s first space satellite (one of several backups built by the USSR) and the U.S. response, a Vanguard satellite made from surviving parts of the actual American satellite that blew up on the launch pad.
The Harmonia Macrocosmica by Andreaus Cellarius. This 1660 atlas included the first published heliocentric depiction of the solar system – “the first published maps where Earth was not the center of the solar system," Walker says. "It divides the age of faith from the age of reason." 
"The Flayed Angel", published in Paris by the anatomist and artist Jacques Gautier d'Agoty in 1745. This three-foot-high, color portrait of a nude, seated woman, viewed from the back with her face turned in three-quarter profile. Her back is slit open up the spine, and her skin and muscles are peeled aside on both left and right to reveal the ribs and spine beneath.
A White House cocktail napkin, circa March, 1942, upon which President Franklin D. Roosevelt briefly outlined his three-point strategy for winning World War II in his own handwriting. The president jotted down his thoughts on the napkin during a Rose Garden meeting with U.S. Army Air Corps General Hap Arnold, who took the napkin back to the Pentagon where it remained classified for many years.
