I have the Annie Proulx book, it is quite practical with plenty of good info and also well written. Bear in mind that these books are mainly about making cider from apples, though there is also plenty of info that relates to using store bought juice. If you just intend to use bought juice there will be more info on the net, including this forum. If you want to learn about pressing apples youtube is a great resource, you can watch a cider press in action. A video is worth a thousand words.
