We all know that Thomas Edison's invention of the light bulb changed the world forever. Otherwise, you would just be reading Dimensions magazine. A collection of Edison's laboratory notes, correspondence, and other significant documents have been released by the Edison Papers Project at Rutgers University to coincide with the 125th anniversary of the electric light bulb in a new volume entitled From Research to Development at Menlo Park (January 1879-March 1881). This fifth volume covers the invention and development of the world's first commercial incandescent electric light and power system.
