Eldred grew up in Florida, graduated from Harvard University in 1966 (philosophy, general studies), and then became a conscientious objector during the Vietnam War.
He was ordered to work for two years as alternative service, at Massachusetts General Hospital in Boston, where he was a respiratory therapist and a chief pulmonary technologist until 1987.
During 2004–05, he lived in an Internet Bookmobile traveling the U.S. visiting schools and libraries and special events to show readers how to print their own free books.
For some years, Eldritch Press ran on a Linux server from Eldred's home and is now hosted by Ibiblio and no longer maintained by him.
[5][6] In 2005, Eldred returned with a permit, secured with the help of the Berkman Center for Internet and Society at Harvard Law School, to print and give away copies of the book, and to demonstrate to readers how to self-publish and regain control of their own culture.
