Computer Lib is a 1974 book by Ted Nelson, originally published by Nelson himself, and packaged with Dream Machines, another book by Nelson. The book had two front covers to indicate its intertwingled nature, and was republished with a foreword by Stewart Brand in 1987 by Microsoft Press. Computer Lib, subtitled "You can and must understand computers NOW," was influenced by Brand's Whole Earth Catalog.Nelson's book is a spirited manifesto that inspired a generation of DIY computer-lovers.
