At CX all long haul airplanes have a worldwide library onboard (single copy).
Additionally there are two sets of "Mini Jepp" containing the departure, destination and primary alternates issued to the operating pilots at dispatch.
The S/O gets a glare if, when the Captain reaches for his chart book, the West charts are there instead of the East charts or vv. Fortunately it can be corrected by injuring one's shoulders and lifting the flight library out of the cupboard!.
I'm with the iPad crew - if only we could get ICAO to agree.
