Almost any UK/Europe specific book on tree ID is a good start. The Collins British Trees book is very popular and very good. A copy of that can often be found in a stationary shop called The Works for a fiver, and other tree ID books crop up in charity shops all the time for probably less than a fiver.
There are a few great threads on this very forum for suitability for carving different types of wood, a quick search often brings up many threads. Some green woodworking books have lists of species and suitability, but that usually only a page or 2.
