The Whole Earth Catalog (WEC) was an American counterculture magazine and product catalog published by Stewart Brand several times a year between 1968 and 1972, and occasionally thereafter, until 1998. The magazine featured essays and articles, but was primarily focused on product reviews. The editorial focus was on self-sufficiency, ecology, alternative education, "do it yourself" (DIY), and holism, and featured the slogan "access to tools". While WEC listed and reviewed a wide range of products (clothing, books, tools, machines, seeds, etc.), it did not sell any of the products directly. Instead, the vendor's contact information was listed alongside the item and its review. This is why, while not a regularly published periodical, numerous editions and updates were required to keep price and availability information up to date. Steve Jobs compared The Whole Earth Catalog to Internet search engine Google in his June 2005 Stanford University commencement speech. When I was young, there was an amazing publication called The Whole Earth Catalog, which was one of the bibles of my generation ... It was sort of like Google in paperback form, 35 years before Google came along. It was idealistic and overflowing with neat tools and great notions. Then at the very end of this commencement speech Jobs quotes explicitly the farewell message placed on the back cover of the last 1974 edition of the Catalog (#1180 October 1974 titled Whole Earth Epilog) and makes it his own final recommendation: "Stay hungry. Stay foolish." The title Whole Earth Catalog came from a previous project by Stewart Brand. In 1966, he initiated a public campaign to have NASA release the then-rumored satellite photo of the sphere of Earth as seen from space, one of the . He thought the image might be a powerful symbol, evoking a sense of shared destiny and adaptive strategies from people. The Stanford-educated Brand, a biologist with strong artistic and social interests, believed that there was a groundswell of commitment to thoroughly renovating American industrial society along ecologically and socially just lines, whatever they might prove to be.
