Well, the legal requirement is that you log your hours. Aerodrome, take-off time, landing time, aircraft type, class, callsign, flight conditions, the capacity you acted in and possibly a few more bits and pieces. How you do that is technically your responsibility. But people seem to be very picky about your logbook style and will point out that you've got the "wrong" one.
The flight school I went to sold me one of those "professional" flying logbooks with enough pages and columns to last me a lifetime and then some. Caused quite a few looks at the motor flying club and the gliding flying club who use a more "compact" form. On the other hand - I've got all my hours in one place with room to spare.
