The electronic logbooks make life very easy and most even have a feature that allows you to print it out in the format of an old fashion logbook. I would keep both, at an interview (later in life if you choose to) or at your upgrade/type rides you will need to show paper logbooks. I would print one out and sign each page then stow it in the freezer or some other fun location, just joking. Oh, and one logbook I would recommend,
