THANKS for this info! I have a huge pile of PopSci and PopMech from the 90s and on, and they're just taking up space. Recently I recycled all of my old Model Railroaders, and now that I know Google Books has PopMech and PopSci, they can go in the hopper, too, freeing up more space in the house. And it's so much easier to find articles via Google Books - a quick search on some keywords produced articles much, much faster than I'd ever find them via flipping through...
