Scientific Advertising
Someone is always reprinting Claude Hopkins. In 1923 he wrote a small book called 'Scientific Advertising'. Hopkins is hopelessly out of date, and amazingly current. He was the outstanding strategist and copywriter of his time. Some of it is dated or has been disproved; times and circumstances have changed. But despite it all, Claude Hopkins laid down guidelines that are too important, too eternal to be forgotten. That's why we've reprinted (in PDF) his words here.
