I have the spiral-bound version, it's cheaper and it's easy to flick thru' if you're airbourne and need the information quickly.
It's a good resource for an initial briefing but, as
FFF says, the aerodrome you're visiting should give you an update when you call them in preflight...and the latest plates are available online from
the AIP via NATS website. I always print out the latest info (for my kneeboard) from here. You'll have to register but it's free.
