This page is to help people who want to do further research, reading, walking etc... by recommending good research material we have found.
Mostly these are recommended books and DVDs relevant to the content of this site. If you want to recommend an item to us, please get in touch.
We own or have read all of these books and recommend them based on that fact alone. There are a lot more books out there on these subjects.
None of these items are actually available from this site. All the links are to amazon.co.uk
