There is no digital edition for this book, so the new edition isnt available anywhere online. Its a huge ass book, so dont expect it to get it free any time soon. If its a refrence kind of book, use this one for now and when the semester ends, your classmates will definitely be selling it . Most of the content should be the same. Check with your peers on that. Only the questions will be different numbered and units in SI instead of US pronably.
