Jepp 27 here as well for my interviews back in 2015. I had my logbook printed and shipped to me by FedEx using their online print services. I did a spiral binding on it with a clear cover and plastic back. The spiral binding allowed me to update the last few pages of the logbook without reprinting the whole thing. I just ordered the last few pages with the spiral binding and cheap covers. It's fairly simple to unscrew the binding, add the updated pages then re-screw in the spiral.
