Since 1978, the Edison Project at Rutgers University has published thousands of documents relating to the inventor of the light bulb and phonograph. Five million pages of documents chronicling the life and achievements of Edison were translated into various languages. The digital edition features 175,000 images, including documents from the Thomas Edison National Historical Park where, in 1962, Edison's West Orange, New Jersey home and lab were declared a national historical site.
The papers of Thomas A. Edison enable readers to learn about Edison's career, work habits and the processes he used in his West Orange lab, which he opened in 1887. The microfilm edition reveals more about Edison's life in the form of notebooks, diaries, business records, correspondences and newspaper articles. Each volume depicts a period in Edison's life. For example, volume eight, covering 1885 to 1887, required review of 11,000 documents by a team of seven professionals and a few undergraduate assistants.
