Google books has begun adding full text magazines. 
They have digitized almost 100 magazines, from cover to cover, showing us the ads, pictures, articles. Each magazine seems to vary how far back in time they go.
They wrote about adding magazines to google books on their blog a year ago.
They are really interesting and fun to look through, plus they are great historic documents. By digitizing every page, it is almost like going to the Periodicals stacks on the second floor of Gleeson and flipping through them on the shelves.
