I own both of the following:
http://www.collins.co.uk/books.aspx?book=27216 (full size)
http://www.collins.co.uk/books.aspx?book=30696 (pocket size)

There is also a 'flash card' version with the book condensed to waterproof cards bound by a rivet. I don't think it's in production any longer.

Both are available via Amazon. I found both in a local book store in the sports section.
