Are these the type of pocket books you are referring to?
(Actually I thought this would be a good opportunity to play with the Photo Upload site)

If this is what you are looking for then JValdes was right on the money, you can get them for free quite easily.
Also the "Pocket Ref" booklet that some of the others refered to is a fantastic little book that's packed full of good info, Princess Auto sells them for around 14 bucks.
