The idea of turning a blog into a book is nothing new, but Kevin Kelly, author and former editor of Wired magazine, has gone all out for his new book, “Cool Tools: A Catalog of Possiblities.” It’s based on the idea of an old catalog, called the Whole Earth Catalog. It’s big, colorful, and it features scannable QR codes attached to many of the nearly 1500 descriptive entries so that you can buy an object you like with a click of the smartphone. Kelly tells Marketplace Tech about the spirit of “Cool Tools,” which comes from a hacker history that started in the 1960s.
