I found this cd on the web a few months ago and purchased it http://www.cafepress.com/tracker2/423461 . It is a well thought out cd with plenty of info and lots of pictures. It is mainly about american mammals and birds but most of the stuff on tracking is the same where ever you go. Its worth adding to the armoury of knowledge.

Ok the cd covers all the basics
The paw principle
Tracking key- its basically a way of narrowing down tracks to a particular spieces.
Dog Vs Cat tracks
Tracking lost people
There is a printable tracking guide and over a hundred mammals and birds are covered with photo's and drawing describing habitat, food etc etc..most are american but theres still otters,mink,fox,badger,grey's and deer
hope that helps you make you mind up.
