The Long Now Foundation is a nonprofit organization that relies completely on private gifts and grants to fund its projects and programs. Every gift is important to us and helps make possible the creation of the 10,000-Year Clock, the formation of a 10,000-Year Library, and the knowledge-sharing work we do. If you'd like to be part of something ambitious, visionary, and downright monumental, consider joining our growing band of supporters. In return, the Clock-Library project offers you the opportunity, as Stewart Brand says, of being instructed, amused and even inspired. You will also be added to our update list, so that you will be the first to learn of the Foundations most recent activities. (Your contribution is tax deductible, of course.Our Tax ID number is: 68-0384748)
