On the subject of Pilot's Notes (PNs), you can buy them from this site on CD-Roms:
Flight Manuals: Aircraft and Helicopter Flight Manuals on CD
If you look at 'Bombers', then scroll down to Jet Bombers and click on the Canberra, you'll find PNs for a whole range of variants.
I bought the Vickers Valiant CD from these people a few years ago and find it very handy.
