The Last Whole Earth Catalog, from June 1971, has been scanned in and is available for electronic browsing pleasure. I was a devotee of the mindset of these folks and a charter subscriber to the quarterly spin-off from the catalogs, known at different times as Whole Earth Review and Coevolutionary Quarterly. I visited them in Sausalito at one point, and had the pleasure of being the next-door neighbor in New Haven of their graphics editor for awhile. (My across-the-street neighbor at the time was the New Haven Zen Center. Nice neighborhood.) In many ways, they were all about hacking the world and your life long before there was electronic hacking. Their closest online literary heir is Kevin Kelly.
